[SH] PR 50694 - SH2A little endian does not actually work

[Oleg Endo]

Hello,

the attached patch addresses PR 50694.
Tested against trunk rev 181301 with:

make -k check RUNTESTFLAGS="--target_board=sh-sim
\{-m2/-ml,-m2/-mb,-m2a-single/-mb,-m4-single/-ml,-m4-single/-mb,-m4a-single/-ml,-m4a-single/-mb}"

For -m2a* it introduces two new failures in:

gcc.target/sh/pr21255-2-ml.c
gcc.target/sh/20080410-1.c

...due to test case parameter handling.  The test cases were made for
little endian only but have not been skipped when ran with big endian
parameters.  The patch also fixes those two test cases.

Cheers,
Oleg
