[testsuite] ARM tests vfp-ldm*.c and vfp-stm*.c

[Janis Johnson]

Tests target/arm/vfp-ldm*.c and vfp-sdm*.c add -mfloat-abi=softfp but
fail if multilib flags override that option.  This patch skips the test
for multilibs that specify a different value for -mfloat-abi.

Tested on arm-none-linux-gnueabi with 43 sets of multlib flags.  OK for
trunk, and later for 4.6?

        * gcc.target/arm/vfp-ldmdbd.c: Skip if multilib flags override
        -mfloat-abi from test.
        * gcc.target/arm/vfp-ldmdbs.c: Ditto.
        * gcc.target/arm/vfp-ldmiad.c: Ditto.
        * gcc.target/arm/vfp-ldmias.c: Ditto.
        * gcc.target/arm/vfp-stmdbd.c: Ditto.
        * gcc.target/arm/vfp-stmdbs.c: Ditto.
        * gcc.target/arm/vfp-stmiad.c: Ditto.
        * gcc.target/arm/vfp-stmias.c: Ditto.
