Subject: [PATCH] Link with shared libyajl in a shared build
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Building yajl in a static context fails in a parallel build:

[ 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 this issue by linking against the shared libyail in a shared build. Apply
this fix also to all other build targets who are linking against the library.

Upstream status: Pending
https://github.com/lloyd/yajl/pull/187

[Update: align with commit 302563539dacb284576a443401cdfd061eb2e1e8 and remove
 linking with libm from test/api/CMakeLists.txt]
