configure: Autodetect TLS bug on ARM with old gcc and apply workaround
Check if compiler being used contains the bug. GCC 7.3.0 is the oldest
version containing the fix, and version 6.3.0 is known to contain the
bug. Bug is only known to appear so far only on ARM32. If the bug is
present, gcc will generate a wrong binary which wil lend up segfaulting
when accessing TLS (__thread) variables under certain conditions.
