Bugzilla Bug 116968

During installation of dev-libs/elfutils this gets printed:

  QA Notice: the following files contain executable stacks
   [...]
  RWX --- --- usr/bin/eu-nm

This occurs both for version 0.108 and 0.118. (And both with gcc-3.3.6 and
gcc-3.4.4, both hardened and vanilla.)

this is due to usage of nested functions in src/nm.c

show_symbols has two nested functions, sort_by_name and sort_by_address

Created an attachment (id=75689) [edit]
elfutils-0.118-no-nested-functions.patch

here's a hackish patch to work around the issue

Looks good enough to me, since the additional data being used by the comparison
function sort_by_name() doesn't change.

An ideal fix would pass the additional state data as a parameter to the
comparison functions, but since the prototype for the function passed to
qsort() is fixed and doesn't have a state pointer this can't be done short of
modifying qsort.

added hack to portage then, thanks
