# We will create a dummy limits.h so the build will not use the one provided by the host distro:
touch /tools/include/limits.h

# Configure options:
# --with-local-prefix=/tools
#     Remove /usr/local/include from gcc's include search path. This is not
#     absolutely essential, however, it helps to minimize the influence of the
#     host system.
# --disable-shared
#     Disables the creation of the shared libraries.
# --disable-threads
#     Prevents GCC from looking for the multi-thread include files, since they
#     haven't been created for this architecture yet. GCC will be able to find
#     the multi-thread information after the libc headers are created.
# --enable-languages=c
#     This option ensures that only the C compiler is built.
