[systemd-devel] [PATCH] build-sys: fix check for efi-lds file

[Mirco Tischler]

Using the DIR macro breaks caching and has no benefit as it only offers
performance improvements when AS_FOR is used with a single element list.
Also --with-lds-dir= was broken as we never set have_efi_lds in this case.
Fix this and check if PATH actually contains the efi-lds file.
