With openwrt/openwrt@8dcc1087602e2dd606e4f6e81a06aee62cfd4f4c, the ARM
FPU compiler options are no longer part of CONFIG_TARGET_OPTIMIZATION.

This updates various packages that look for NEON/VFP support to search
CONFIG_CPU_TYPE instead.

The CONTRIBUTING.md requests an (or multiple) SPDX identifier for GPL
licenses. But a lot of packages did use a different, non-SPDX style with a
"+" at the end instead of "-or-later".
