bug#32367: 2.2.4 hangs when a script uses a module that calls sigaction

[Derek Upham <sand@blarg.net>]

I’m not having luck with the patch.  Current commit is bbe6daa76 (stable-2.2).  Running

  ./autogen.sh && ./configure --prefix=$HOME/guile-2.2 PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/lib64/pkgconfig:/usr/lib/pkgconfig:/usr/share/pkgconfig && make clean all install

builds clean and I can repro the problem with

  $HOME/guile-2.2/bin/guile -s ../signal-test

The patch applies cleanly, but then the same build commands fail:

    GUILEC sxml/apply-templates.go
