Thanks very much for the report ... corrected in svn.

On May 19, 2016 a commit was made with the comment "remove unused flag" that remove the "-fobjc-nonfragile-abi" from the INTERNAL_OBJCFLAGS variable if the user requested the use of non fragile abi option.  My guess is that the intention was to remove it from the INTERNAL_LDFLAGS variable (the next line in the makefile) which would have made more sense given the comment.

But this change pretty much broke the GUI and BACKEND packages for anyone trying to build the GNUstep libraries for use with clang and ARC.  Attempting to use the -fobjc-arc flag while compiling a GUI application results in an executable that won't load because of a mismatched ABI configuration.

The only way to fix this is to add the "-fobjc-nonfragile-abi" flag back to the INTERNAL_OBJCFLAGS variable in common.make and then rebuild all of the GNUstep libraries.

See attached screen shots for the details of the commit that broke this.
