In addition, `redhat-rpm-config` re-selects the built-in default
tuning in the `gcc` package. These settings are:
* **armhfp**: `-march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=hard`
selects an Arm subarchitecture based on the ARMv7-A architecture
with 16 64-bit floating point registers. `-mtune=cortex-8a` selects
tuning for the Cortex-A8 implementation (while preserving compatibility
with other ARMv7-A implementations). `-mabi=aapcs-linux` switches to
the AAPCS ABI for GNU/Linux.
* **i686**: `-march=i686` is used to select a minmum support CPU level
of i686 (corresponding to the Pentium Pro). SSE2 support is
enabled with `-msse2` (so only CPUs with SSE2 support can run the
