boehmgc: drop musl flags, per upstream's note (!) (#157625)

Browse source 
0938316e05 (commitcomment-63005097)

Resulting binaries are identifical according to diffoscope
(other than embedded /nix/store/.../ paths).

FWIW, going back through versions we've packaged, the most recent
instance where these flags produced differing outputs was in 7.6.8
(comparing $out's only, FWIW).
