[PATCH][AArch64] Get %c output template tests to pass for -fPIC

[Kyrill Tkachov]

Hi all,

When I added the tests for the %c output template for aarch64 I did not take 
into account that compiling them with -fPIC would fail. This patch fixes them to 
use the 'S' constraint to get them to work.

Ok for trunk?

Tested on aarch64-none-elf/-fPIC

Thanks,
Kyrill
