My best bet is to add it as a multilib during testing:
Index: gcc/config/i386/t-pmm_malloc
===================================================================
--- gcc/config/i386/t-pmm_malloc (revision 119099)
+++ gcc/config/i386/t-pmm_malloc (working copy)
@@ -4,3 +4,6 @@
mm_malloc.h: $(srcdir)/config/i386/pmm_malloc.h
rm -f $@
cat $^ > $@
+
+MULTILIB_OPTIONS=m128bit-long-double
+MULTILIB_DIRNAMES=ld128bit
Additionally, to test my modifications to subreg_regno_offset() and
subreg_offset_representable(), I'm using wrappers around the two functions
to compare the results of the new and old ones and abort if they aren't
identical.
