# Since binutils 2.22, DT_NEEDED flags aren't copied for dynamic outputs.

# Always add PaX flags section to ELF files.
# This is needed, for instance, so that running "ldd" on a binary that is
# PaX-marked to disable mprotect doesn't fail with permission denied.
./pt-pax-flags.patch
# Bfd looks in BINDIR/../lib for some plugins that don't
# exist. This is pointless (since users can't install plugins
# there) and causes a cycle between the lib and bin outputs, so
# get rid of it.

# Help bfd choose between elf32-littlearm, elf32-littlearm-symbian, and
# elf32-littlearm-vxworks in favor of the first.

./disambiguate-arm-targets.patch
# For some reason bfd ld doesn't search DT_RPATH when cross-compiling. It's
# not clear why this behavior was decided upon but it has the unfortunate
# consequence that the linker will fail to find transitive dependencies of
# shared objects when cross-compiling. Consequently, we are forced to
# override this behavior, forcing ld to search DT_RPATH even when
# cross-compiling.
