  Changed paths:
    M m3-sys/cminstall/src/config-no-install/Darwin.common

  Log Message:
  -----------
    - use -g1 instead of -g to not crash on Darwin

  - split SYSTEM_CC into SYSTEM_CC and SYSTEM_CC_LD
   SYSTEM_CC is for compiling C++
   SYSTEM_CC_LD is for linking, but using the C/C++ compiler

  -x c++ is on the first only

 Still have to port the fix for:
 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66509
 which breaks assembling libm3
