Solaris ships with (some) non-executable shared libraries, and
this change breaks x11-links where /usr/openwin is read-only (eg.
chroot) because it tries to chmod symlinks:

=3D=3D=3D> [Automatic none shared object handling]
/usr/pkg/share/x11-links/lib/libXol.so: installed without execute permissio=
n; fixing (should use [BSD_]INSTALL_LIB)
chmod: WARNING: can't change /usr/pkg/share/x11-links/lib/libXol.so
*** Error code 1

I don't know if test -h is supported on IRIX5, and it's easier to just
not do it unless needed. it also causes deviation from the default
behaviour on some platforms which I think should be avoided (your
recent libtool sanity fixes are a definite plus here!).

should I add _OPSYS_SHLIB_EXEC to platform/*.mk ?

grant.
