Log Message:
lang/spidermonkey52: fix a build breakage on PowerPC

PowerPC (at least, the variants used on hardware typically supported by
pkgsrc) does not offer the gamut of hardware-backed atomic instructions
that relatively recent versions of SpiderMonkey demand. Fall back to
using GCC's libatomic, so this builds and runs on that architecture.
