[bug #39721] File conflicts between installations with different prefixes

[Josh Triplett]

Follow-up Comment #2, bug #39721 (project grub):

The data below comes from bzr revno 5086.

~/src/grub-bzr$ ./configure --program-prefix=i386-pc- --target=i386
--with-platform=pc && make DESTDIR=/tmp/grub-i386-pc-inst install
[...]
~/src/grub-bzr$ make distclean # build broken with missing headers otherwise
[...]
~/src/grub-bzr$ ./configure --program-prefix=x86_64-efi- --target=x86_64
--with-platform=efi && make DESTDIR=/tmp/grub-x86_64-efi-inst install
[...]
~/src/grub-bzr$ diff -u

So, grub-mkconfig_lib depends on the program prefix, yet does not itself
include that prefix, so two installations with different program prefixes will
conflict.
