 --enable-maintainer-mode  enable make rules and dependencies not useful
 			  (and sometimes confusing) to the casual installer
 --enable-multilib       build many library versions (default)
 --disable-dependency-tracking  speeds up one-time build
 --enable-dependency-tracking   do not reject slow dependency extractors
+--disable-symvers       disable symbol versioning for libssp
 --enable-shared[=PKGS]  build shared libraries [default=yes]
 --enable-static[=PKGS]  build static libraries [default=yes]
 --enable-fast-install[=PKGS]
 optimize for fast installation [default=yes]
 --disable-libtool-lock  avoid locking (might break parallel builds)
 --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
 --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
 --with-pic              try to use only PIC/non-PIC objects [default=use
 both]
 --with-gnu-ld           assume the C compiler uses GNU ld [default=no]
+--with-gcc-major-version-only
+use only GCC major number in filesystem paths

 CC          C compiler command
 CFLAGS      C compiler flags
 LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
