Change gcc_target_options to return std::string
This patch was inspired by a recent review that recommended using
std::string in a new implementation of the gcc_target_options gdbarch
function. It changes this function to return std::string rather than
an ordinary xmalloc'd string.
I believe this caught a latent memory leak in compile.c:get_args.
Tested on x86-64 Fedora 29.
