[PATCH, ARM] fix bootstrap on trunk

[Robert Nelson]

On both my arm gcc builders (Sheevaplug & Beagleboard).  I've been
getting this error on trunk while trying run the gcc bootstrap script:

Sheevaplug: http://rcn-ee.homeip.net:81/dl/gcc/SVN-154188-trunk-armv5tel/trunk-error.log
Beagleboard: http://rcn-ee.homeip.net:81/dl/gcc/SVN-154200-trunk-c-armv7l-256/trunk-c-error.log

This patch fixes these errors on the Sheevaplug and Beagleboard.

Sheevaplug Full Build (2.5M), now running the testsuit:
http://rcn-ee.homeip.net:81/dl/gcc/SVN-154250-patch-trunk-c-armv5tel/trunk-c-build.log
Beagleboard, Build still in progress, (should be complete in another
couple hours), but has passed that error:
http://rcn-ee.homeip.net:81/dl/gcc/SVN-154250-patch-trunk-c-armv7l/

Patch: http://rcn-ee.homeip.net:81/dl/gcc/SVN-154250-patch-trunk-c-armv5tel/trunk-c-patch.diff
