# Configure options:
# --disable-profile
#     Builds the libraries without profiling information.
# --enable-add-ons
#     Use all the add-ons it finds.
#     crypt and localdata are now part of glibc.
# --enable-kernel=2.x.x
#     Compile the library for support of linux 2.6.x kernels.
#     The kernel version specified must not be newer than the
#     version of the kernel running on the build machine.
# --with-headers=/tools/include
#       Forces glibc to use the linux-libc-headers installed
#       in /tools/include, rather than those on the host, which
#       may be too old to support needed functionality.
# --with-binutils=/tools/bin
#     Strictly speaking this switch is not required. But it
#     does ensure nothing can go wrong with regard to what
#     Binutils programs get used during the Glibc build.
# --without-gd
#     Prevents the build of the memusagestat program, which
#     strangely enough insists on linking against the host's
#     libraries (libgd, libpng, libz, and so forth).
# --without-selinux
#       When building from hosts that include SELinux functionality
#       (e.g., Fedora Core 3), Glibc will build with support for
#       SELinux. As the LFS tools environment does not contain support
#       for SELinux, a Glibc compiled with such support will fail to
#       operate correctly.
