gdbm 1.8.3: install libgdbm_compat

It has been built but not installed by default, while 1.11 builds and
installs it.

Fixed when build non_gplv3 + perl:
powerpc64-wrs-linux-gcc -m64 -mhard-float -mcpu=e6500
--sysroot=/mnt/docker/test_p/bitbake_build/tmp/sysroots/fsl-t2xxx
-Wl,-O1 -Wl,--hash-style=gnu -Wl,--as-needed -
fstack-protector -shared NDBM_File.o  -o
../../lib/auto/NDBM_File/NDBM_File.so   \
   -lgdbm -lgdbm_compat         \

ld: cannot find -lgdbm_compat
collect2: error: ld returned 1 exit status
Makefile:473: recipe for target '../../lib/auto/NDBM_File/NDBM_File.so' failed
