third_party_mesa3d/bin/mklib
Ian Romanick 9eecb03226 Make sure mklib sees the definition of CC and CXX. Make mklib respect 
the definitions of CC and CXX on Linux.  This fixed build issues with
sunos5-gcc and build issues on GCC 2.x Linux when CC and CXX are set
to a GCC 3.x compiler.

# Make a shared library.
# Basically do a switch/case depending on the OS and make a shared (or static)
# library conforming to that OS.
# Usage:
# mklib [options] objects ...
# Options:
# -o LIBRARY specifies the name of resulting library
# ("-o GL" for example, might result in "libGL.so" being made)
# -major N specifies major version number (default is 1)
# -minor N specifies minor version number (default is 0)
# -patch N specifies patch version number (default is 0)
# -lLIBRARY specifies a dependency on LIBRARY
# -LDIR search in DIR for library dependencies
# -cplusplus link with C++ runtime
# -static make a static library (default is dynamic/shared)
# -install DIR move resulting library file(s) to DIR
# -arch ARCH override using `uname` to determine architecture
# -archopt OPT specify an extra achitecture-specific option OPT
# -noprefix don't prefix library name with "lib" or any suffix
#
# The library name should just be "GL" or "GLU", etc. The 'lib' prefix
# will be added here if needed, as well as the ".so" or ".a" suffix,
# etc (unless the -noprefix option is used).
#
# objects should be: foo.o bar.o etc.o
#
# Environment variables recognized:
# CC C compiler command
# CXX C++ compiler command
#
#
# Option defaults
#
