bug#39999: make install fails on mac (Catilina, Guile-3.0.1)

Hi,
 make install on the last Guile 3.0.1 fails on my Mac (Catilina) with the following message


 ../build-aux/install-sh -c -d '/Users/mgubi/t/guile3-usr/include/guile/3.0/libguile'
 /usr/bin/install -c -m 644 version.h scmconfig.h '/Users/mgubi/t/guile3-usr/include/guile/3.0/libguile'
/Library/Developer/CommandLineTools/usr/bin/make  install-data-hook
 /usr/bin/install -c -m 644 libguile-3.0-gdb.scm				/Users/mgubi/t/guile3-usr/lib/libguile-3.0.a-gdb.scm
sed: -e: No such file or directory
make[5]: *** [install-data-hook] Error 1
make[4]: *** [install-data-am] Error 2
make[3]: *** [install-am] Error 2
make[2]: *** [install] Error 2
make[1]: *** [install-recursive] Error 1
make: *** [install] Error 2


I found that the following change to libguile/Makefile go around the problem

INSTANTIATE = \
  $(SED) -i '' -e 's,[@]pkgdatadir[@],$(pkgdatadir),g'                          \
            -e 's,[@]pkglibdir[@],$(pkglibdir),g'                               \
            -e 's,[@]GUILE_EFFECTIVE_VERSION[@],$(GUILE_EFFECTIVE_VERSION),g’


HTH,
