Tested on a cross to armv8l-unknown-linux-gnueabihf where the failing
testcase is restored, and on aarch64-linux-gnu where no change is seen
on the aarch64.exp suite.  Also tested on arm64 Darwin for aarch64.exp
and aarch64-darwin.exp.

OK for trunk, or some alternative would be better?

The change applied in r14-5760-g2a46e0e7e20 changed the behaviour of
functions with assembly like:

bar:
__acle_se_bar:

Where both bar and __acle_se_bar are globals refering to the same
function body.  The old behaviour overrides 'bar' with '__acle_se_bar'
and the scan tests for that label.

The change here re-allows the override.

Case like this are not legal Mach-O (where two global symbols cannot
have the same address in the assembler output).  However, given the
constraints on the Mach-O scanning, it does not seem that it is
necessary to skip the change (any incorrect case should be easily
evident in the assembler).

gcc/testsuite/ChangeLog:

        * lib/scanasm.exp: Allow multiple function start symbols,
        taking the last as the function name.
