guile1 doesn't work

[Werner LEMBERG]

Trying to compile 55d9ad39, I get this:

  scripts/build/out/help2man \
    out/lilypond-invoke-editor > out/lilypond-invoke-editor.1
  Can't exec "out/lilypond-invoke-editor":
    No such file or directory at scripts/build/out/help2man line 193.
  help2man: can't get `--help' info from out/lilypond-invoke-editor
  make[1]: *** [out/lilypond-invoke-editor.1] Error 2
  make[1]: Leaving directory `scripts'

Reason is that guile1 is somehow accepted by the configure script, but
the GUILE configure variable isn't set properly to `/path/to/guile1'
(in stepmake/aclocal.m4) so that @GUILE@ (at the top of
`lilypond-invoke-editor.scm') doesn't get replaced properly.
