[PATCH,testsuite] fix gcc.target/arm/long-calls-*.c in Thumb-2 mode

The patch below fixes several failures for tests on Thumb-2 targets.

- GCC doesn't (currently) generate sibling calls in Thumb-2 mode;

- The tests are looking for PLT markers, which don't get generated for
  Thumb-2, and may eventually not get generated for ARM mode.

Neither of these things is core to the tests themselves: the tests are
looking for the presence of short or long calls.

Tested on arm-none-eabi.  OK to commit?

	* gcc.target/arm/long-calls-1.c: Tolerate the lack of sibling
	calls and/or PLT markers.
	* gcc.target/arm/long-calls-2.c: Tolerate the lack of sibling
	calls and/or PLT markers.
	* gcc.target/arm/long-calls-3.c: Tolerate the lack of sibling
	calls and/or PLT markers.
	* gcc.target/arm/long-calls-4.c: Tolerate the lack of sibling
	calls and/or PLT markers.
