stand/efi: Pass --no-dynamic-linker to ld.bfd >= 2.34.

Browse Source 
ld.bfd in binutils 2.34+ now reports an error in more cases for custom
ldscripts that do not place PHDRs in a LOAD segment.  However, EFI
binaries are not dynamic binaries which need PHDRs, so pass
--no-dynamic-linker to disable this check.
