the intent of the test is to test the just-produced Guile binary, so
if that binary is not on PATH, the test suite should be fixed so that
it is on PATH.

I'm responsible for that comment, so when I ran the test suite, it did
find the Guile binary in the build tree.  Maybe something happened in
the meantime that it doesn't now, but the right fix is IMO definitely
not to replace Guile with sh, as relying on sh being available is not
going to work on Windows.

Please instead try to figure out why guile is not on PATH.  Running
meta/guile might be better, but isn't that a shell script that
requires sh as well?
