Define "brokenRedHatKernel = true" in $NIXPKGS_CONFIG to build a system that works on Red Hat Linux, i.e. that is based on glibc version 2.5. Furthermore, this patch fixes a number of gcc 4.3.3 build errors in glibc 2.5 that occur on both x86 and x86_64. The older version of this library is still useful for running Nix on a Red Hat host. Newer version of glibc fail to detect the kernel's capabilities correctly (due to mad patches applied to the kernel by Red Hat). The individual changes are: * Re-activated glibc 2.5 in all-packages.nix. * Fix incomplete header search path in bootstrap tools. Gcc-wrapper sets "-B<prefix>" to tell the compiler about its installation root. Unfortunately, the setting doesn't add $gcc/lib/gcc/*/*/include-fixed to the search path. That directory is required, however, because it contains the system-specific "limits.h" file, and the glibc 2.5 builds tries to find that file via #include_next. * Support intrinsic functions like __signbit() or atof() correctly to avoid compile-time conflicts. * Switch to NPTL. Linuxthreads is no longer supported. * Added a meta attribute to glibc package. * Updated nixUnstable to version 0.13pre15614 from trunk. The previous version failed regression tests. * Fix more strict type checking in binutils since 2.18.50.0.3. Without this patch, the build failed on x86, saying: ../sysdeps/i386/fpu/ftestexcept.c: Assembler messages: ../sysdeps/i386/fpu/ftestexcept.c:33: Error: suffix or operands invalid for `fnstsw' svn path=/nixpkgs/branches/stdenv-updates/; revision=16037
