configure: add --disable-rt option
This option disables any attempts in configure to create dependency on
stuff requiring linking to librt.so and libpthread.so, in this case this
means clock_gettime(CLOCK_MONOTONIC, &mt).
We were in need to build curl which doesn't link libpthread.so to avoid
the following bug:
