 Use libpthread instead of libthr on FreeBSD

 Since #847 we have used libthr due to reported hangs with FreeBSD's
 KSE-based M:N pthread implementation. However, this was nearly 12 years
 ago and today libpthread seems to work fine. Moreover, adding -lthr to
 the linker flags break when used in conjunction with -r when gold is
 used (since -l and -r are incompatible although BFD ld doesn't
 complain).

 Test Plan: Validate on FreeBSD
