 You might consider the MIPS approach where we also used to have an issue 
with various targets using different emulations while still wanting to 
verify non-default ones (legitimate for several MIPS targets) and came up 
with an arrangement where the emulations selected are derived from the 
target triplet.  Yes, it's a zoo, but so is the MIPS target collection.

 See the `abi_ldflags' setting in ld/testsuite/ld-mips-elf/mips-elf.exp 
for details.
