Apply changes in logger introduced with:
    4f3d7e86ad6d20bdf8ba29fcd09fb5d6dd2bddb6 in sflphone repo

Refs #56437

SFLPHONE_SRC was a duplicate of SFLPHONE_SRC_DIR

Choose correct libraries dependind on ARCH
Some dependencies adapt their lib name based on target arch.

Build is still mono-arch, you either build for arm XOR x86.

are in sflphone/daemon/...

Does nothing for the time being
