I  put  a patch and sources of ports for  m32r ont the following site.
http://www.linux-m32r.org/eng/download.html#content_1_1_1

The patdh is the following.
http://www.linux-m32r.org/gnu/src/glibc-ports-m32r-2.3.5-20051101.patch

> Then use glibc-2_3-branch to checkout ports as well.
I  used  libc and ports glibc-2_3-branch  on 20051101.
When I used the sources,  there were some failure to build. 
The attachment is a patch for libc to avoid the problem.

libc/ChangeLog

2005-11-01  Kazuhiro Inaoka <inaoka.kazuhiro@renesas.com>

	* Makeconfig (libc.so-gnulib): Added -lgcc_s$(libgcc_s_suffix)
	to avoid undefined _Unwind_Find_FDE.

	* elf/elf.h (R_M32R_REL32): Added a relocation number.

	* sysdeps/unix/sysv/linux/futimes.c (__futimes): Use __libc_fcntl
	instead of INLINE_SYSCALL macro to avoid undefined __NR_fcntl.
	(M32r doesn't provide __NR_fcntl.)

	* sysdeps/unix/sysv/linux/i386/fcntl.c: Include "kernel-features.h"
	instead of "../kernel-features.h".
	(ports/sysdeps/unix/sysv/linux/m32r/fcntl.c include this file.)
