[PATCH 1/3] contrib/regression/btest-gcc.sh: Handle multiple options.

[PATCH 1/3] contrib/regression/btest-gcc.sh: Handle multiple options.

[Hans-Peter Nilsson]

Deliberately not using getopt.  Tested by adding a line right after this
code echoing $dashj, $add_passes_despite_regression, and $1 (then exit)
and checking that I got it right for combinations of -j j4
--add-passes-despite-regression.

-- >8 --
This is a long-standing bug: passing "-j --add-passes-despite-regression"
or "--add-passes-despite-regression -j" caused the second option to be
treated as TARGET; the first non-option parameter.

	* btest-gcc.sh (Option handling): Handle multiple options.
