I almost always build with sparc_sunc so make it the default.
I only do sparc_gcc for testing that the build still works with gcc.

for motif.

Solaris/x86.  There should be no functional changes for either other
x86 ports or for the sparc port.

tools/create-target.sh:
o If lisp variant is solaris using Sun C, setup default motif config
  to use Sun C too.

motif/server/Config.solaris_sunc:
o New config file for building motifd using Sun C.

sun4_solaris_gcc and sun4_solaris_sunc configs are now obsolete, but
we leave the around for now.

Tested both configs and they work.

lisp/Config.sparc_common:
o New file for common config for gcc and Sun C builds on Solaris

lisp/Config.sparc_gcc:
o New file for building on sparc/solaris with gcc

lisp/Config.sparc_sunc:
o New file for building on sparc/solaris with Sun C

tools/create-target.sh:
o Change default from sun4_solaris_gcc to sparc_gcc to use new
  configuration.

  FreeBSD changes.
o Update MOTIF_VARIANT stuff to recognize the new x86_freebsd and
  x86_linux LISP_VARIANTs.

subshell.

Use a new (much smaller) Config.x86_freebsd, named consistently with (some) other files.

code/bsd-os.lisp:
o Automatically define :freebsd4 and :elf, if compiling lisp has them
  defined.

tools/create-target.sh:
o Support FreeBSD.

tools/setenv-scripts/freebsd-features.lisp:
o New file with default (commented out) example for FreeBSD.

tools/build.sh:
o If gmake exists, assume it is GNU make and use it instead of make.

tools/create-target.sh:
o Auto-detect FreeBSD and use FreeBSD_gencgc as the default config.

what this is supposed to do.

  based on uname -s.  Currently only supports Linux and Solaris.
o Moved all the feature frobbing stuff from this file to separate
  files in the new setenv-scripts directory.  (Should we get rid of
  these?  However, they do serve as useful documentation of what
  features might exist in a given platform.)
