This change breaks build at least on Cygwin, ./configure fails with:

checking whether target compiler is working... no
configure: error: cannot compile for the target

The link test in grub_PROG_TARGET_CC fails due to missing '__main' 
symbol from libgcc. According to gcc 4.3.2 man page, '-nostdlib' usually 
requires '-lgcc'.
