[Bug target/37912] New: cannot build arm-gcc with --with-march=armv7-a

[weizhong at broadcom dot com]

I was trying to build an arm-linux-gcc with options "--with-march=armv7-a".
./configure fails, the error message is,

Unknown arch used in --with-arch=armv7-a

That is because SVN commit 132837 for file
svn://gcc.gnu.org/svn/gcc/trunk/gcc/config.gcc has not been merged into gcc-4.3
branch.
