[Buildroot] [PATCH] yajl: disable parallel build

The yajl build system contains a race condition, which gets triggered by
high BR2_JLEVEL settings - It tries to link the executable gen-extra-close
against libyajl before it is created:

[ 21%] Linking C executable gen-extra-close
[ 26%] Building C object src/CMakeFiles/yajl_s.dir/yajl_buf.c.o
/home/test/autobuild/instance-3/output/host/opt/ext-toolchain/bfin-uclinux/bfin-uclinux/bin/ld.real: cannot find -lyajl

Fix it by disabling parallel build.
