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... :-(

1 There are at least three weird glitches in the Makefile:
2 - the test operator is a dual-equal sign (==) when it should be a single one (=);
3 - the exclude options are not accepted as is by GNU tar;
4 - how on earth could KERNEL_SOURCE possibly be equal to DEVEL_PREFIX ???
6 We (Cedric DUVAL and I, Yann E. MORIN) are not quite sure why it is that way.
7 We're not quite sure either on how to solve this.
9 What we need is to built a toolchain; in no way we need to install the linux headers.
10 ==> systematically exclude them from the [s]tar command.
12 This patch is inspired by the svn repository of uClibc as of 20060209.
