Don't use __timezone when using uClibc

Don't use __timezone when using uClibc

It appears that plinux.h is a generated file, created by autoconf on a
glibc system, so it naturally outputs a config for glibc. This patch
changes one of the settings so that it doesn't break when used with
uClibc.

This small patch makes the plinux.h platform configuration file also work on
uClibc systems (it appears to have been generated on a glibc system).

I considered using the LIBC_GLIBC macro which is defined in
build/build_config.h, but I'm not sure if that's safe to include here.

Can you update README.chromium (item 2) to refer to this CL?  Adding something
like this will do:

- Apply the CL at https://codereview.chromium.org/15973007/ to plinux.h 

FYI, I'm gonna update ICU to 51.2 next week.

Thanks.

Since CQ doesn't appear to be hooked up- can you please land this for me?
