 rts: Fix build when linked with gold

 As reported in #12812, the runtime system fails to build when linked
 with gold due to a missing dependency on libpthread.

 Additionally, rts/package.conf.in uses the WORD_SIZE_IN_BITS macro
 defined by MachDeps.h, which it does not #include. Fix this.

 Test Plan: Validate with gold linker
