$! Command-line options:
$!
$!    32            Compile with 32-bit pointers.
$!    BIGENDIAN     Compile for a big endian host.
$!    CCQUAL=x      Add "x" to the C compiler qualifiers.
$!    DEBUG         Build in debug mode.
$!    CLEAN         Only perform clean after the previous build.
$!    TESTS=(x)     Build library tests. Comma separated test names or leave
$!                  empty to build all the tests.
$!                  Example 1 (curtain tests): TESTS=(pmem,puthread)
$!                  Example 2 (all tests): TESTS
$!    RUN_TESTS     Runs all tests.
$!    NOLIB         Skip library buidling. Useful when you want to rebuild
$!                  particular tests.
