arm64 doesn't have a epoll_wait() system call but a logic error stopped libuv from falling back to epoll_pwait(). This bug was introduced in commit libuv/libuv@67bb2b5 ("linux: fix epoll_pwait() regression with < 2.6.19") which sadly exchanged one regression for another. This commit is a back-port of libuv/libuv@1d8332f and should help get the ARMv8 buildbot in better shape.

Notable changes: * C++ API: Fedor Indutny contributed a feature to V8 which has been backported to the V8 bundled in io.js. SealHandleScope allows a C++ add-on author to seal a HandleScope to prevent further, unintended allocations within it. Currently only enabled for debug builds of io.js. This feature helped detect the leak in #1075 and is now activated on the root HandleScope in io.js. (Fedor Indutny) #1395. * ARM: This release includes significant work to improve the state of ARM support for builds and tests. The io.js CI cluster's ARMv6, ARMv7 and ARMv8 build servers are now all (mostly) reporting passing builds and tests. - ARMv8 64-bit (AARCH64) is now properly supported, including a backported fix in libuv that was mistakenly detecting the existence of `epoll_wait()`. (Ben Noordhuis) #1365. - ARMv6: #1376 reported a problem with Math.exp() on ARMv6 (incl Raspberry Pi). The culprit is erroneous codegen for ARMv6 when using the "fast math" feature of V8. --nofast_math has been turned on for all ARMv6 variants by default to avoid this, fast math can be turned back on with --fast_math. (Ben Noordhuis) #1398. - Tests: timeouts have been tuned specifically for slower platforms, detected as ARMv6 and ARMv7. (Roman Reiss) #1366. * npm: Upgrade npm to 2.7.6. See the release notes (https://github.com/npm/npm/releases/tag/v2.7.6) for details.
