[bug#67824] [PATCH core-updates 0/6] Run builds in C.UTF-8 locale

I experienced a similar thing just now (I had removed #:parallel-build?
#f from ‘binutils-mesboot0’):

Here ‘conftest’ is a zombie, which means that the shell running
./configure (gash-boot-0.3.0) did not call ‘waitpid’ (bug #1).  There’s
another bunch of .guile-real zombie processes (child processes of ‘make
DESTDIR= RPATH_ENVVAR=LD_LIBRARY_PATH
TARGET_SUBDIR=i686-unknown-linux-gnu
bindir=/gnu/store/pkaxhawivjhhff55ncglr30c6d9dzlaz-binutils-mesboot0-2.20.1a/bin
[…]’).

Thus the ‘conftest’ process got reparented to the Guile process that
runs the build script (PID 1), and then we run into (bug #2):
