Fixes for ARM gas testsuite

[Nick Clifton]

Hi Richard,

: Can we avoid references to sections such as .rdata?  a.out doesn't
: have these sections which makes the test unsuitable for targets
: based on those platforms.  For these tests, what is wrong with just
: pushing the data into the text segment?

Nothing at all.  In fact there is no need for any data in the test
file at all, so I have eliminated the entire ".section .rdata" stuff at
the beginning of the file and changed the .word to reference an
undefined, external symbol (that does not start with a period).

Cheers
