Description: Use RTLD_GLOBAL so that other dynamic libary can find library symbols.
For example, this fix enable compiled lisp file to find symbol defined in libeusgeo.so
$ cat intersection3-test.l
(eval-when (load) (geo::line-intersection3 #f(0 0 -1) #f(0 0 1) #f(0 -1 0) #f(0 1 0) 0.001))
$ EUSDIR=`pwd` ./Linux64/bin/eusg '(progn (compile-file "intersection3-test.l" :o "intersection3-test.o") (load "intersection3-test.so")(print *user*)(unix::exit))'
c.f.) https://github.com/android/ndk/issues/201Index: euslisp/lisp/c/loadelf.c
