configure.ac: fix cross compiling warning

There is a warning while cross compiling which triggered a
failure by do_qa_configure
...
|configure:12652: checking for gzread in -lz
|configure:12677: mips-poky-linux-gcc  -meb -mabi=32 -mhard-float
 -L/lib conftest.c -lz   >&5
|ld: warning: library search path "/lib" is unsafe for cross-compilation
...

While do the lib checking, do not add '-L${Z_DIR}/lib' to LDFLAGS could fix it.

Upstream-Status: Inappropriate [oe specific]
