Subject: [bug#74290] [PATCH v4 49/58] gnu: bootstrap: %bootstrap-glibc: Also fix libm.so.
Date: Sun, 24 Nov 2024 08:55:12 +0100

On the 64bit Hurd, glibc-2.39's libm.so is also a linker script.  This fixes
having it refer to

    /gnu/store/eee...-glibc-cross-x86_64-pc-gnu-2.39/lib/libm.so.6
    /gnu/store/eee...-glibc-cross-x86_64-pc-gnu-2.39/lib/libmvec.so.1

* gnu/packages/bootstrap.scm (%bootstrap-glibc)[arguments]: When building for
the 64bit Hurd, also substitute libm.so linker script.  Update the regexp to
also cater for libh[urduser] and libm[achuser].
