generate a crt0 and crt1 file. Most arches still need
to be updated to call __uClibc_start_main() rather than
__uClibc_main().

build a crt0.o and a crt1.o. crt1.o will support ctors and dtors if
such support is enabled. One more gratuitous toolchain support issue
is thereby removed...

configurable, so people who do not need or want ctor/dtor support
can disable it and make their binaries a little bit smaller.

mips where I had made a mess
|

how uClibc handles _init and _fini, allowing shared lib constructors and
destructors to initialize things in the correct sequence. Stefan ported the SH
architecture. I then ported x86, arm, and mips. x86 and arm are working fine,
but I don't think I quite got things correct for mips.

(undefined reference to `main') when the .o file containing main was contained
in an static library(a '.a' ar archive). It turns out that due to its single
pass nature, GNU ld was failing to pull it into the build. This sticks a dummy
reference to main() into crt0.o, so that when an application is linked with the
main() function in a static library, we can be sure that main() actually gets
linked in.

these stubs were preventing the real stuff from working properly.
