GMP and MPFR are no longer a sub-component of gcc (config-wise).
Build and install GMP and MPFR for the target.
Use the target GMP and MPFR to build the native gdb.
Have separate extra_config for cross gdb, native gdb and gdbserver.
Check native GMP and MPFR in //.

Glibc does not build: asm/page.h not found

As of linux-2.6.25, asm/page.h is no longer exported.

This means the glibc up to and including 2.6 will not build against headers

exported from linux-2.6.25 and up. Starting with glibc-2.6.1, patches are

available that solves the issue. Switch to at least 2.6.1 if you can, or try

to backport the fix (should be quite easy).

dmalloc does not build

This broken build has been observed for big endian ARM with glibc and NPTL,

and with i686 with glibc and NPTL.

This has not been fully investigated yet. There is a name clash with strdup,

where it is a macro somewhere, and dmalloc tries to re-declare a strdup

function in dmalloc.h, but the declaration is overwritten with the macro

expansion, and thus the build is broken.

The common denominator seems to be NPTL.
