been working on a new config system on and off for about 6 months
now, but I've never been fully satisfied. Well, I'm finally am
happy with the new config system, so here it is. This completely
removes the old uClibc configuration system, and replaces it with
an entirely new system based on LinuxKernelConf, from
http://www.xs4all.nl/~zippel/lc/
As it turns out, Linus has just merged LinuxKernelConf into Linux
2.5.45, so it looks like I made the right choice.
I have thus far updated only x86. I'll be updating the other
architectures shortly.

with the new naming

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)

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.

and when using real functions. Make things be more portable by
providing a default C routine to locate the got.

before we build shared libc. We need to build shared libc before libdl.

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.

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.

III and me. I've been working on stripping out arch dependant stuff and
replacing it with generic stuff whenever possible.
