add some more GCC args that indicate profiling

Relevant documentation:
https://gcc.gnu.org/onlinedocs/gcc/Instrumentation-Options.html
https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html

Also relevant is the need to avoid remote compilation when the compiler
might try to use a .gcda file generated locally during a profiling run
(common occurrence during profile-guided optimisation).
