[Buildroot] [PATCH 1/2] arch: drop BR2_GCC_TARGET_CPU_REVISION option

[Thomas Petazzoni]

In commit 325bb37942f8d3826dab9dc6e88b25234e67a2cf, support for the
Blackfin architecture was removed. This was our only use of
BR2_GCC_TARGET_CPU_REVISION, and since this config option somewhat
complicates the calculation of the --with-cpu/-mcpu option values,
let's drop it.
