People are supposed to patch s|-pthread|${PTHREAD_LIBS}| too, because
PTHREAD_LIBS are not guaranteed to be equal to -pthread forever.
So...according to what you means,
we should update the "12.12 Threading libraries" section....?
"12.12 Threading libraries
The threading library must be linked to the binaries using a special
linker flag -pthread on FreeBSD. If a port insists on linking
-lpthread or -lc_r directly, patch it to use PTHREAD_LIBS variable
provided by the ports framework. This variable usually has the value
of -pthread, but on certain architectures and FreeBSD versions it can
have different values, so do not just hardcode -pthread into patches
and always use PTHREAD_LIBS.
Note: If building the port errors out with unrecognized option
'-pthread' when setting PTHREAD_LIBS, it may be desirable to use gcc
as linker by setting CONFIGURE_ENV to LD=${CC}. The -pthread option is
not supported by ld directly.
