contrib: Avoid sysmobts/oc2g toolchain ld crashes building new libosmocore
Some gcc version (< 7.3.0) on ARM generate wrong code for __thread
variables that crash at runtime. It seems, due to some unknown reason, that we
are not affected by this bug with toolchain from poky pyro (6.4.0). However,
libosmocore as of e188b8cd98f599468fbb200c7d590de955daf761 applies some
CFLAGS="-mtls-dialect=gnu2" to workaround the issue automatically. But same
toolchain contains an "ld" that crashes when those flags are applied.
Fortunately, libosmocore provides a way to disable the workaround, and since
we are not affected by the bug, we are fine with that. If the toolchain had
the TLS runtime bug, then we'd had to build with -O0. Can be probably dropped
once we move to newer toolchain.
