Description of problem:

When rebuilding from the elilo srpm under Fedora, we encounter errors as below
and failed to build the binary rpm:

It seems that a link to /usr/lib/libz is missing when compiling
efibootmgr-0.5.3/src/efibootmgr/efibootmgr. Adding a '-lz' to the variable
'LIBS' in efiefibootmgr-0.5.3/src/bootmgr/module.mk can fix it.
