Patch from Ralf Corseipus to fix latent configure problems suddenly triggered:

The breakdown:

  • CC_FOR_TARGET and CXX_FOR_TARGET were not correctly re-read from autoconf's configuration cache (config.cache)
  • If <target>-[gcc|g++] was not found while running configure, the config macros tried to use other (wrong) compilers (e.g. cc).

Changes:

  • New RTEMS_PROG_CC macro (aclocal/prog-cc.m4).
  • New RTEMS_PROG_CXX macro (aclocal/prog-cxx.m4)
  • Moved a shell script fragment from configure.in to a new m4-autoconf macro (New file: aclocal/tool-prefix.m4)
  • Minor changes to configure.in

I tested it with linux/posix (native gcc/primary libc) and
sh-rtems/gensh1 on a linux host and didn't notice any bugs
related to the problems mentioned above. There seem to be
more bugs with the posix bsp, but I consider them minor as
the build run completed successfully. It is just too late
for me to attempt to fix them now.
