[systemd-devel] autoconf cache collision in check for gnuefi

I get the following error when doing ./configure --enable-gnuefi:
checking for /usr/lib/gnuefi/elf_x86_64_efi.lds... no
checking for /usr/lib/elf_x86_64_efi.lds... (cached) no
configure: error: *** gnuefi support requested but files not found

even though the second file exists on my system.

In the lines: configure.ac:1186
                [AS_FOR([DIR], [EFI_LDS_DIR], ["${efiroot}/gnuefi"

AC_CHECK_FILE doesn't expand the DIR variable and creates the cached
variable ac_cv_file_DIR_elf_x86_64_efi_lds, which is then falsely
reused for all DIRs. I'm not sure if this is an autotools or systemd

systemd version: current git
autoconf version: 2.69
on Arch Linux
