buildroot patches for gcc-4.2

[Miguel Angel Alvarez]

Hi

Due to problems with gcc 4.1.1 release with my m68k architecture, I am 
trying to build up a toolchain based on uclibc and the source code in 
the svn trunk of gcc.

I have also added the patches of buildroot for gcc-4.2, but when I try 
to compile gcc I obtain the following.

I suppose that the problem is that __convert_from_v has changed its API 
in commit 114591 of gcc, but the patch of buildroot does not reflect this.

I have made a complementary patch to 200-uclibc-locale.patch.

It seems to work, but I would appreciate if you check it.

I know I should send this to the mailing list of buildroot but I am not 
able to subscribe to it...
