[massive] add support for alternative C libraries (currently only glibc/eglibc)

Browse Source 
other (related) changes:
 - kernel headers are now installed using "make headers_install" on 2.6
 - target names now contain an openwrt "vendor" tag (e.g. mips-openwrt-linux-gnu)
 - build directory names now contain gcc/libc name/version
 - default cpu for x86 is now i486 (required to build glibc/eglibc)

Fixes a MIPS build problem (unrelated to NPTL)

Subject: New NPTL patches for crosstools and MIPS NPTL patches....
Greetings.
I have uploaded the latest NPTL patch for crosstool-0.34. I have also
uploaded a tarball of the patches necessary to build a MIPS NPTL
cross toolchain. To build a MIPS NPTL toolchain you will need the
released version of binutils-2.16 and the absolute latest GCC and
glibc code from the HEAD of cvs. Use the 'demo-mips-nptl.sh' script
to build the toolchain. Please report bugs or issues to the crossgcc
mailing list. Here is the link off of my FTP site:

[Note: BOOTSTRAP_GCC is set by crosstool.sh when invoking make install-headers]
