hadoop-2.2: build error on FreeBSD

[Dmitry Sivachenko]

Hello!

FreeBSD does not need "-ldl" when linking programs that use dlopen() (dlopen is 
in libc).
Now I am getting the following error trying to compile hadoop-2.2.0 on FreeBSD:

     [exec] /usr/bin/cc  -fPIC  -g -Wall -O2 -D_REENTRANT -D_GNU_SOURCE 
-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64   -shared

-B/usr/home/mitya/hadoop-2.2.0-src/h/usr/bin/ld: cannot find -ldl


Can you please adjust your build system not to use "-ldl" on FreeBSD?

Thanks!
