Using the macros in config/linux.h rather than duplicating them helps
stop future bitrot, and repairs existing bitrot (4 choices for libc in
linux.h, fewer in the rs6000 files not that it matters much). Also
fixes the fact that __gnu_linux__ was always defined rather than just
when glibc was the libc of choice.

Create a framework for putting function bodies in export data. At
present only empty functions will be put there, and they will be
ignored on import. Later patches will get this to the point of
supporting inlining of (some) functions defined in other packages.

The mul64 attribute in types.md causes some confusion as it is used to represent
aarch32 instructions that do widening multiplication to generate 32->64 bit results.
But these types are shared with aarch64, which has native 64-bit multiplication operations.
Those are currently not properly represented, which I will fix in follow-up patches.
For now, this patch renames the mul64 attribute to widen_mul64 to more clearly communicate its meaning.
It mechanically updates all users of that name in config/arm/ (there are no users in config/aarch64).
There is thus no change in behaviour.

(widen_mul64): ... This.

When throwing an Exception in the Fiber the backtrace generation
crashes. This happens because backtrace does not func the stack bottom.
Using '.cfi_undefined x30' tells the debug info that the value in the lr
is unknown, which seems to be the nicest way to stop the unwinder.
Setting x30 to 0 is another option, however it still creates one invalid
frame in gdb, so the .cfi variant is used here instead.
Backport from upstream druntime 2.083.

With multiple threads, using an unprotected static variable to check
whether recursion has occured isn't valid, as one thread might have
modified the variable, thus causing another thread to incorrectly
conclude that recursion has occured. This patch avoids this problem
by using a thread-specific variable for the recursion check.
Regtested on x86_64-pc-linux-gnu.
