v8: cherry-pick uclibc build patch from upstream
Original commit log follows:
Restore V8_LIBC_UCLIBC as a libc option.
As uClibc defines __GLIBC__ in an attempt to look like glibc,
V8_LIBC_GLIBC was true for uClibc as well. Checking for uClibc
before glibc fixes this and restores the correct behavior.
