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.
