Now I get it.  This version is more selective about which multilibs
are skipped.  I tested it by using multilib test flags for all valid 
values for -march, with and without -mthumb as appropriate for the 
arch.  The ones that are now skipped are the ones that used to fail
with complaints from the compiler.

Is this OK?

	* gcc.target/arm/pr40887.c: Require at least armv5.
	* gcc.target/arm/pr51835.c: Avoid conflicts with multilib flags.
	* gcc.target/arm/pr51915.c: Likewise.
	* gcc.target/arm/pr52006.c: Likewise.
	* gcc.target/arm/pr53187.c: Likewise.
