official lang/gcc14 package builds are broken, at least for armv7: "error: attempt to use a poisoned identifier" and more

Also: no member named 'fancy_abort' in namespace 'std'

Such is associated with not using STANDARD_BOOTSTRAP for armv7, given GCC's historic lack of keeping builds of everything working for just direct use of clang++/libc++ or the like.

The specific change that got back into this issue was:

-LANGUAGES:= c,c++,objc,fortran
+LANGUAGES:= c,c++,objc,fortran,jit

It is the jit part of the build that fails to build as stands.
