toolchain: allow for stupid toolchains
check_arm_abi builds a test C file to check that the toolchain is
working correctly, with the output redirected to /dev/null.
However, some toolchains (OSELAS 2014.12.0, for instance) foolishly
append ".gdb" to the output filename for an intermediate file, causing
an attempt to write to /dev/null.gdb, which obviously fails.
Fix this by adding changing the output to a temporary file, which is
later removed along with any other "suffixed" files.
