[PATCH] testsuite, Darwin : Do not claim 'GAS' for cctools assembler.

[Iain Sandoe <iain@sandoe.co.uk>]

Hi,

Although the cctools assembler is based of GNU GAS, it is from a
very old version (1.38) which does not support many of the features
that the target supports test is expecting***.

tested on i686 and x86_64 darwin versions using the cctools as.
OK for master?

thanks
Iain

*** I guess we could be more clever and parse the output to find a version
and then alter the supports condition to “gas NN”, but I don’t currently
have cycles to implement that.
