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.
