[Buildroot] [PATCH] bind: fix intermittent build issues with high BR2_JLEVEL

[Jan Heylen <heyleke@gmail.com>]

From: Peter Korsgaard <jacmet@sunsite.dk>

Build sometimes breaks with:

libtool: link: `unix/os.lo' is not a valid libtool object
make[3]: *** [rndc-confgen] Error 1
make[3]: *** Waiting for unfinished jobs....
make[4]: Leaving directory `/scratch/peko/build/bind-9.6-ESV-R4/bin/rndc/unix'

So disable parallel builds.

[Jan Heylen: This patch was removed with commit c36b5d89c5616f7ca0a7295cbb5c231606beb71e
by Gustavo Zacarias <gustavo@zacarias.com.ar> but the problem still occurs,
so disabling parallel builds again]
