# compiler, which will be recorded, and used in all subsequent extension
# (and other) builds.

# The "strip" perl script, works around a verification error caused by a
# UFS bug (stripping a multi-link file breaks the link, and sometimes causes
# the wrong file to be stripped/unstripped).  By using the "strip" perl script,
# it not only causes the correct file to be stripped, but also preserves the
# link.
#
# The cc/gcc scripts take a -no64 argument, which causes 64-bit architectures
# to be removed, before calling the real compiler.
