 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]
---enable-gold           use gold instead of ld
+--enable-gold[=ARG]     build gold [ARG={both}[/{gold,ld}]]
 --enable-libada         build libada directory
 --enable-libssp         build libssp directory
 --enable-build-with-cxx build with C++ compiler instead of C compiler
 --disable-ppl-version-check    disable check for PPL version
 --disable-cloog-version-check  disable check for CLooG version
