toolchain-external: move the sysroot check to helper function

Browse Source 
The sysroot toolchain support check is duplicated at two locations in
the external toolchain infra. So move it inside the
check_unusable_toolchain helper that is called when the toolchain
package is configured (TOOLCHAIN_EXTERNAL_CONFIGURE_CMDS).

The check in TOOLCHAIN_EXTERNAL_INSTALL_SYSROOT_LIBS can be safely
removed since it's already done in check_unusable_toolchain helper.

The check in TOOLCHAIN_EXTERNAL_INSTALL_TARGET_LIBS was removed by
2a87b64f8e8a832a351f8552eb032e4b18431949.
