[committed] libphobos: Remove qsort_r compat to fix *-freebsd14 [PR123633]

[Iain Buclaw]

Hi,

This patch is a backport of a change already in mainline.

Assemblers cannot handle `pragma(mangle, "qsort_r@FBSD_1.0")', as the
symbol name is not the same as symbol version.

Regtested on x86_64-freebsd16.0, committed to releases/gcc-15.

Regards,
Iain.
