 Optional Features:
 --disable-option-checking  ignore unrecognized --enable/--with options
 --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
 --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
 --disable-shared        don't provide a shared libgcc
+--disable-gcov          don't provide libgcov and related host tools
 --enable-vtable-verify    Enable vtable verification feature
 --enable-version-specific-runtime-libs    Specify that runtime libraries should be installed in a compiler-specific directory
 --enable-maintainer-mode
 enable make rules and dependencies not useful (and
 sometimes confusing) to the casual installer
 --disable-largefile     omit support for large files
 --enable-decimal-float={no,yes,bid,dpd}
 			enable decimal float extension to C.  Selecting 'bid'
 			or 'dpd' choses which decimal floating point format
 			to use
+--enable-cet            enable Intel CET in target libraries [default=no]
 --enable-explicit-exception-frame-registration
 register exception tables explicitly at module
 start, for use e.g. for compatibility with
 installations without PT_GNU_EH_FRAME support
 --enable-tls            Use thread-local storage [default=yes]
