Do not use `test ... -a ...'.

[Ralf Wildenhues]

Spotted, and pushed this trivial patch.  (Yes, on HP-UX all shells know
this, but being consistent is easy here.)

Cheers,
Ralf

        Do not use `test ... -a ...'.
        * libltdl/m4/libtool.m4 (_LT_LINKER_SHLIBS) [hpux10, hpux11]:
        Replace test -a with test && test.
