chicken-and-egg problems when building gcc toolchains.

enable -falign-functions if avilable.

Autodetect target architecture by asking the compiler.

things are working perfectly (perhaps I shouln't think so much)
|
|
appropriately so). Leave this hidden and set to a sane default
since nobody should really need to change it...
|

Here is the basic theory of operation:
SHARED_LIB_LOADER_PATH/ <The location where the shared lib
loader will be installed and where the
compiler will cause apps to look for it.>
DEVEL_PREFIX/
bin/ <contains gcc, ld, etc for setting PATH=$DEVEL_PREFIX/bin:$PATH>
lib/ <contains all runtime and static libs>
include/ <Where all the header files go>
SYSTEM_DEVEL_PREFIX/
usr/bin/ <contains arch-uclibc-gcc, arch-uclibc-ld, etc that
might be installed by a .deb or .rpm into /usr/bin,
but can happily live under DEVEL_PREFIX>
PREFIX
This is prepended during 'make install's allowing you to shift things to
be installed under some alternate location (such as when building a .deb)

issues, and syns things (as far as I am willing) with Dave Schleef's
tree. We may need to go another round or so, but we do seem to be
converging...

few tiny fixups here and there from me. Seems to work just fine and
will hopefully be a bit better behaved.

else fails. Let <arch>-uclibc-gcc --uclibc-use-build-dir set the
shared lib loader to the one in the builddir's path.

all arches till they add in an libc/sysdeps/linux/<arch>/bits/syscalls.h
file. Sorry about there, there was no other way...

working around a missing header file in the compiler shipped with the
uCsimm and uCdimm. This should make the folk in Toronto happy, since
now they can use the latest CVS version of uClibc.

TARGET_PREFIX to allow more flexibility. Also modified the gcc wrapper
to do the right thing if -Wl,--dynamic-linker,xxx is passed on the command
line. The gcc wrapper will also check the env variable UCLIBC_GCC_LDOPT
for a dynamic linker option at runtime (although command line arg overrides
the env variable).

from libm float function support. Also, move all Config files out of the
main directory.

tree is less messy now (which helps), all libraries are placed into
uClibc/lib when compiling, all libraries now use a consistant mechanism
for being built, all libraries use a consistant naming scheme where the
lib name includes the uClibc version number, which makes ldconfig
happy and willing to work with us.
-Erik

dropped into a uClibc/lib dir when compiling, which will make life a
bit easier when installing and cleaning up. Preface uClibc with 'lib'
so ldconfig will recognize it as a library. Make all libraries have the
uClibc version number attached, making upgrades possible by using the
traditional symlink to the .so name plan.

was using one name and the ld.so-1 dir was using another (they happened
to be the same). Fix that.

are compiling for an arch for which uClibc has an ld.so or not,
and otherwise sets things up to use the system ld.so.

when appropriate,

This required we use _LIBC instead of __LIBC__ to be consistent with glibc.
This had some sideffects in sys/syscalls.h. While fixing things, I made
everything use __set_errno() for (eventual) thread support.

defining things to "0" in the disabled case to outright undefining them, lest
code that does an "#ifdef FOO" get inadvertantly triggered. Remove now
unneeded lines from Rules.mak which makes the command line smaller and avoids
redundancy (since this stuff is now pulled in via features.h).

Also fixes 2 very important malloc bugs! Anyone using malloc (esp mmu-less)
should update and recompile.

m68k started. Should be just sysdeps/linux/m68k left to
hack at this point...

etc, support. Now compiles with 2.0.x kernels for armnommu.
