cgcc: use only the cc command to determine $gcc_base_dir

Capture the c-compiler command, in the $ccom variable, in order to
later invoke the compiler without extraneous command-line options.
In particular, use the $ccom variable in order to cleanly invoke the
compiler when setting the $gcc_base_dir variable.
