Don't pass -m32 to libcc1 on arm-linux
When I run gdb.compile/ tests on arm-linux, I get the following fails,
(gdb) compile code -- ;^M
arm-none-linux-gnueabihf-gcc: error: unrecognized command line option '-m32'; did you mean '-mbe32'?^M
Compilation failed.^M
(gdb) compile code (void) param^M
arm-none-linux-gnueabihf-gcc: error: unrecognized command line option '-m32'; did you mean '-mbe32'?^M
Compilation failed.^M
(gdb) FAIL: gdb.compile/compile-ops.exp: compile code (void) param
This patch fixes it by implementing gcc_target_options gdbarch method
for arm-linux to override option "-m32".
