[Fabrice Fontaine]

Set CMAKE_C_COMPILER_TARGET to BR2_ARCH to fix the following arm build
failure raised since bump to version 2.0.6 in commit
d2249821d3f30202ca2a35ad24918378d9a0a0e8:

-- Detecting C compile features - done
-- Arch not recognized, falling back to cmake arch: 'l'
-- Basearch 'l' not recognized, defaulting to 'x86'.
-- Basearch of 'l' has been detected as: 'x86'

[...]
