Have the glibc build use the cross-objdump, rather than the host one.
On some distros (eg. Fedora), the native objdump can not interpret objects not for the native system, and thus fail.
This commit adds a new patch against glibc-2.7 that introduces OBJDUMP_FOR_HOST, wich, if set, overides the detected objdump.
Note: bizarely enough, glibc already has code to detect the cross-objdump, but that does not work for an unknown reason... :-(
