Usage: configure [options]
Options:
Build options:
--help print this message
--log=yes|no|FILE file configure log is written to [config.err]
--target=TARGET target platform tuple [generic-gnu]
--cpu=CPU optimize for a specific cpu rather than a family
${toggle_extra_warnings} emit harmless warnings (always non-fatal)
${toggle_werror} treat warnings as errors, if possible
(not available with all compilers)
${toggle_optimizations} turn on/off compiler optimization flags
${toggle_pic} turn on/off Position Independant Code
${toggle_ccache} turn on/off compiler cache
${toggle_debug} enable/disable debug mode
${toggle_gprof} enable/disable gprof profiling instrumentation
${toggle_gcov} enable/disable gcov coverage instrumentation
Install options:

${toggle_install_bins} control whether binaries are installed
${toggle_install_libs} control whether libraries are installed
${toggle_install_srcs} control whether sources are installed

NOTES:
Object files are built at the place where configure is launched.
All boolean options can be negated. The default value is the opposite
of that shown above. If the option --disable-foo is listed, then
the default value for foo is enabled.
