configure: Allow disabling workaround for TLS bug in old ARM gcc versions
Some toolchains (such as sysmobts 201705 one) containing the TLS bug on
old ARM gcc versions (<7.3.0) also crash if the initial workaround found
is aplied (CFLAGS="-mtls-dialect=gnu2"). In that scenario, let's provide
a way to disable the workaround (to avoid "ld" crashing) and warn the
user about requirement to build with -O0 to avoid runtime crashes.
