BR2_PACKAGE_GETTEXT=y might be enabled even if BR2_NEEDS_GETTEXT is
not set, and in this case, we should not link against libintl, because
it may not exist, for example with glibc toolchains.

[Thomas:
- fix commit title
- powertop wants libintl unconditionally, so make sure
BR2_PACKAGE_GETTEXT is selected when BR2_NEEDS_GETTEXT is set, and
add gettext to the dependencies.
- add missing comment about thread dependency.
- add missing dependency on host-pkgconf, without which powertop
cannot find libnl.
- patch src/Makefile.am to not pass -fstack-protector, which fails
to build if the toolchain does not have SSP support.
- rename patch powertop-autotune.patch to confirm to the patch
naming convention.]
