[PATCH 0/5] Add support for aarch64-nto-qnx

[Clément Chigot]

This serie adds support for the QNX Neutrino operating system over
aarch64 architecture.
It creates a new aarch64-nto linker emulation applying nto.em
over aarch64elf.em. For now, this nto.em has not be included
for other nto targets (sh-nto, arm-nto, etc).

Clément Chigot (5):
  configure: add new target aarch64-*-nto*
  readelf: add support for QNT_STACK note subsections
  ld: add support of QNX stack arguments for aarch64nto
  ld/testsuite: add aarch64nto to ld-aarch64
  ld/testsuite: disable ilp32 tests for aarch64-qnx
