[Buildroot] [PATCH] package/tz: fix incorrect timezone setting for uclibc

[Yann E. MORIN]

Scott, All,

On 2015-07-31 14:25 +0800, Scott Fan spake thusly:
> According to the doc file from <uclibc-src>/docs/
> Glibc_vs_uClibc_Differences.txt, the uclibc library read the
> TZ environment variable, or the /etc/TZ file; the /etc/TZ file
> should be a single line, ending with a newline, containing the
> TZ setting.  For example: echo CST6CDT > /etc/TZ
> 
> Whereas the tzdump cmd would output two lines like this:
>   # Asia/Shanghai
>   CST-8
> 
> This make the uclibc could not read the correct TZ setting, therefore
> e.g. the 'busybox date' cmd always show the UTC timezone.
> 
> This fix remove the redundant first line from the tzdump output.
