A patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:

    Here is another patch to hopefully enhance rtems' configuration.

    Motivation: Try to support other c-compilers besides gcc (I tried to
    build rtems under Solaris using sun's WSPro c-compiler).

    Here is a couple of small patches concerning the host compiler
    configuration, which fix/work-around the worst problems when using sun's
    WSPro c-compiler.

    Changes:
        * Replaced make/compilers/gcc.cfg with make/compilers/gcc.cfg.in, ie.
          gcc.cfg is generated by configure now.
        * Removed a line containing a hard-coded "gcc" from gcc.cfg (BUG-fix).
        * Add -g to host compiler flags only if configure reported -g to work
        * Add -Wall to host compiler flags only if configure reported that the
          host compiler is gcc (WSPro's cc chokes on -Wall).
        * Some modifications to make/Makefile.in
        * Adapted make/custom/default.cfg to the new location of gcc.cfg

    BTW, gcc.cfg/gcc.cfg.in seems to be full of unused code (DEBUG-VARIANTS
    etc.) which deserves to be cleaned up, IMO.

    IMO, a similar patch should be applied to gcc-target-default.cfg
