Wait, no: the argument for `$CPPFLAGS' also applies to `$LDFLAGS'.  That
is, if `-L' flags are passed through `$LDFLAGS' to `configure', like
`-L/path/to/gmp', then they must be reported by "guile-config link".

Admittedly, it has the undesirable side-effect of reporting completely
unrelated link flags as well.  Unfortunately, I'm not sure we could
reliably filter `$LDFLAGS'.

Thanks,
