This is the plan. When I say "workaround" there is an implied
"temporary" as I expect that the underlying issue is fixable.
The worst cases I can imagine are either patching out various
"using ::acoshl" lines in the GCC cmath header or injecting some
dummy definitions into the newlib math.h header like:
> long double acoshl(long double) __attribute__((error("Not implemented")));
