Hello!
Sorry for re-sending this patch. My e-mail was incorrectly set up. It
should be fixed now. Please ignore the previous post from my xemaps.com
address.
Here's an alternate patch for the issue that appeared on Fedora 8. The
linker adds a "build ID" (.not.gnu.build-id) by default. That section
makes objcopy create output files about 128M long when asked to use
binary format. Needless to say, they are not suitable as grub images.
Also, the build ID section breaks the test for objcopy in the configure
script.
This patch is less intrusive than the one I posted earlier, so I hope it
will be accepted.

* configure.ac: Test if '--build-id=none' is supported by the
linker. Add it to TARGET_LDFLAGS if possible. Build ID
interferes with objcopy.
* aclocal.m4 (grub_PROG_OBJCOPY_ABSOLUTE): Use LDFLAGS when
linking, so that build ID doesn't break the test.
