             Bug #: 14476
           Summary: test-installation.pl fails on x86_64
           Product: glibc
           Version: 2.16
            Status: NEW
          Severity: normal
          Priority: P2
         Component: build
        AssignedTo: unassigned@sourceware.org
        ReportedBy: bruce.dubbs@gmail.com
                CC: carlos@systemhalted.org
    Classification: Unclassified


When building glibc-2.16, 'make install' runs test-installation.pl.  This
fails.

I traced it down to an error in soversions.mk.  A literal extract:

...
ld.so-version=$(if $(abi-64-ld-soname),$(abi-64-ld-soname),ld.so.1)
all-sonames+=ld=$(ld.so-version)
...

The value for ld.so-version crashes test-installation.pl.  It should be
ld-linux-x86-64.so.2.  abi-64-ld-soname is defined correctly in
sysdeps/unix/sysv/linux/x86/Makefile, but it is not getting into soversions.mk.

This problem seems to have been introduced into Makeconfig on 26 May 2012 in
commit 0ab0291b84b45f2389a019af2c88bf5169d14f64

We can work around this by simply deleting the test-installation.pl line from
the Makefile, but that doesn't seem to be a real fix.
