Added CC=${CC} to the EXTRA_OEMAKE parameter and it now builds it as ARM lib.
The strip error is gone but file isn't stripped:libxmlpcp.so:
ELF 32-bit LSB shared object, ARM, version 1 (SYSV), dynamically linked, not stripped

However strangely still missing it in the rootfs, but I will continue my search.
