bug#37876: Regression in MAKE-GCC-TOOLCHAIN after core-updates merge

[Carl Dong]

Hi all,

I believe there's been a recent regression w/re MAKE-GCC-TOOLCHAIN. I'm unable
to guix build the following minimal reproducer:

--8<---------------cut here---------------start------------->8---
(use-modules (gnu packages commencement)
             (gnu packages gcc)
             (gnu packages base))

(make-gcc-toolchain gcc glibc-2.27)
--8<---------------cut here---------------end--------------->8---

My guix describe output:
Generation 33   Oct 22 2019 15:07:03    (current)
  guix f5d6c88
    repository URL: https://git.savannah.gnu.org/git/guix.git
    commit: f5d6c88d0f5e1556295c1a19c46ddfcb7a23107f

The build failure logs can be found here:
