Comment (by jpflori):

 Whatever, I guess that passing -no-undefined to libtool just overrides its
 default behavior to pass -undefined dynamic_lookup to ld on OS X.

 So we have two solutions:
 * only pass -no-undefined where it is really needed, that is on Cygwin,
 * use _NSGetEnviron() routine from <crt_externs.h> to define environ on OS
 X.
