Follow-up Comment #2, bug #28335 (project grub):
No, this patch does not fix the problem I reported, configure stops with the
same error (see below).
I believe that this error is triggered in the macro
grub_PROG_OBJCOPY_ABSOLUTE, which is called before the line that is changed in
the proposed patch. This macro is defined in acinclude.m4. The following
patch works on my system.
