hexagon: fix symbols defined in global namespace

[androm3da]

Update compiler_builtins to 0.1.124:

Some call targets were defined with aliases that could conflict with symbols from a user's program. These aliases have now been deleted or qualified with two leading underscores.

• Includes [hexagon] Remove aliases w/o leading __ compiler-builtins#682
• Should fix hexagon-unknown-none-elf cannot build core, "symbol 'fma' is already defined" #129823

It looks like this is superseded by #129992.

It looks like this is superseded by #129992.

Hmm - so should I close this PR in favor of that one?

@Mark-Simulacrum should we review/merge this PR as-is, or defer to the superseding one with more content?

The updated should be done in all relevant places so we don’t wind up with multiple versions. I just approved #129992, I’ll just close this one since that one should have it covered.

Will also add a fixes tag to that PR to close the hexagon issue.
