extern-inline: avoid compilation error with HP-UX cc

Reported by Richard Lloyd in
<http://lists.gnu.org/archive/html/bug-texinfo/2013-02/msg00030.html>.
* m4/extern-inline.m4 (_GL_INLINE, _GL_EXTERN_INLINE):
Suppress extern inline with HP-UX cc.  This should be safe,
though it may hurt performance.  Perhaps someone with some HP-UX
experience can come up with a higher-performance fix.

    Suppress the use of extern inline on Apple's platforms,
    as Libc-825.25 (2012-09-19) is incompatible with it; see
    <http://lists.gnu.org/archive/html/bug-gnulib/2012-12/msg00023.html>.
    Perhaps Apple will fix this some day.  */
