[Pkg-cmake-team] Bug#1098956: Info received (Bug#1098956: Acknowledgement (cmake: FTBFS on hppa - /usr/bin/ld: warning: exec has a LOAD segment with RWX permissions))

[Dave Anglin]

It is not clear why the warning was forced on all architectures.  We have the following
code in ld/configure.tgt:

# By default the linker will generate warnings if it is creating an
# executable stack or a segment with all three of read, write and
# execute permissions.  These settings are not appropriate for all
# targets however, so we can change them here:

if test "${ac_default_ld_warn_rwx_segments}" = unset; then
  case "${targ}" in
      # The CRIS and V850 default linker scripts yields just one segment
      # as intended, so a rwx segment warning is not helpful.
      # The HPPA's and SPARC's PLT sections use a constructed trampoline
      # hence it needs to have a RWX segment.
      # Many MIPS targets use executable segments.
