Parallel builds were disabled in 2016 by buildroot commit

In 2020 upstream added two commits which fix parallel builds

https://github.com/pjsip/pjproject/commit/78683646c8bc670ec730a42494e075f671a08e28
to version 2.11 which was added to buildroot with commit
2c7ad667ec4a25226848baba809e492ca0ff06da.

Tested with -j100.
