             Bug #: 55821
           Summary: Release tarballs (unconditionally) install
                    libquadmath.info when libquadmath is not supported
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libquadmath
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: gerald@pfeifer.com


On platforms that do not support libquadmath, GCC release tarballs
still install libquadmath.info.

This was reported to me for sparc64-unknown-freebsd* and
powerpc-unknown-freebsd*, I am pretty sure it applies to
all platforms that do not support libquadmath.

This applies to releases only, not for our weekly snapshots,
since (only) the former contain pre-built .info files.

Actual outcome: libquadmath.info is installed unconditionally.

Desired outcome: libquadmath.info is only installed where libquadmath
is support (as correctly done already by our weekls snapshots, though
not our releases).
