A log of the command "make" would be more useful than a log of the command
"make -j8", because the latter intermingles the output of different
compilations running in parallel. For example, here it looks like the
error messages are coming from the compilation of getopt1.c:

These logs are more interesting:

On glibc systems, getgroups is expected to work. So, the cause is already
to be found during the autoconfiguration.

The error comes from the fact that you have a -L option, the directory in this
option was actually used to locate a shared library (libwcs.so.6 in this case),
but the runtime linker cannot find this shared library.
There are two easy workarounds:
(a) set the environment variable LD_LIBRARY_PATH=/usr/local/lib
before the configuration,
(b) pass LDFLAGS="-L/usr/local/lib -Wl,-rpath,/usr/local/lib".
In the case (a) the binaries that you build will only work when
LD_LIBRARY_PATH=/usr/local/lib is still set. In the case (b) the
binaries will work without this environment variable.
