[Bug libc/10096] New: Adjust STT_GNU_IFUNC to support targets with OPDs (hppa, ia64)

["carlos at codesourcery dot com" <sourceware-bugzilla at sourceware dot org>]

Targets that use OPDs can't directly call through the function descriptor
returned by DL_FIXUP_MAKE_VALUE. The following patch adds STT_GNU_IFUNC support
for targets with OPDs. The patch creates a new macro DL_FIXUP_CALL_VALUE in
dl-lookupcfg.h. The new macro is used to call the value returned by
DL_FIXUP_MAKE_VALUE, and on targets with OPDs the macro can be used to adjust
the way in which the returned function descriptor is called.

No regressions on hppa-linux-gnu. ia64 will need a similar patch.

If a core maintainer thinks this is a good solution, please apply the libc patch.

Thank you.
