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.
