[Buildroot] [PATCH v2] package/qt5/qt5base: handle sse2/sse3/ssse3/sse4.1/sse4.2/avx/avx2 configuration

[Peter Seiderer]

The Qt configure auto detection (and announced runtime detection
feature) failes (see e.g. [1]), so override the configuration
with the buildroot determined settings.

Changes v1 -> v2:
  - use 'else ifeq' (suggested by Thomas Petazzoni)
  - fix typo (anounced vs. announced)
  - clarify no-avx512 comment

Notes:
 - suggested by Arnout Vandecappelle [2]
