            Bug ID: 28671
           Summary: hurd: Build failure with PIE
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: hurd
          Assignee: unassigned at sourceware dot org
          Reporter: siddhesh at sourceware dot org
                CC: samuel.thibault@ens-lyon.org, tschwinge at sourceware dot org
  Target Milestone: ---

When building i686-gnu with build-many-glibcs.py and this patch[1] (with the
hunk changing sysdeps/mach/hurd removed) to enable PIE across the board in
glibc, the Hurd target fails as follows:

build-many-2/install/compilers/i686-gnu/lib/gcc/i686-glibc-gnu/11.2.1/../../../../i686-glibc-gnu/bin/ld:
cannot find build-many-2/build/glibcs/i686-gnu/glibc/csu/rcrt0.o: No such file
or directory
collect2: error: ld returned 1 exit status
make[3]: *** [../Rules:269:
build-many-2/build/glibcs/i686-gnu/glibc/support/test-run-command] Error 1

This prevents PIE from being enabled by default for hurd.  I'll post the final
link of the commit and clearer steps to reproduce when it actually goes in.

Thanks, could you please remove definition of PIE_UNSUPPORTED in
sysdeps/mach/hurd/configure.ac so that PIE is enabled on hurd?
