New binutils 2.22 causing havoc on many AUR packages

Question

Many posts around here showing that this is a common problem. ld has changed behaviour and has broken some packages that don't explicitly link to libraries.
My example: Minutor
gcc -Wl,--as-needed -o minutor minutor.o mapviewer.o colorschemes.o `pkg-config --libs gtk+-2.0` MinutorMap/MinutorMap.a
/usr/bin/ld: MinutorMap/MinutorMap.a(nbt.o): undefined reference to symbol 'gzopen'
/usr/bin/ld: note: 'gzopen' is defined in DSO /usr/lib/libz.so.1 so try adding it to the linker command line
/usr/lib/libz.so.1: could not read symbols: Invalid operation
collect2: ld returned 1 exit status
make: *** [minutor] Error 1
Related info I found on the Fedora Wiki
All posts so far suggest adding things to LDFLAGS but none of them have worked for me yet. Found on thread "EMC2 Simulator (CNC) PKGBUILD":

--as-needed isn't the problem here, it's transitive linking. See the first item in the ld changelog for binutils 2.22. There's two options:
- add "-Wl,--copy-dt-needed-entries" to LDFLAGS
- add "-lXt" to LDFLAGS
Either way, this should be fixed upstream. You should explicitly link against any library you depend on.
This didn't work for me whether I put it in the PKGBUILD or /etc/makepkg.conf
Any ideas?
EDIT: It appears that the LDFLAGS are not being added to the gcc line shown above no matter where I put the additional LDFLAGS. Perhaps I'm doing it wrong.

I maintain one package in AUR and it hit this issue. From this I extrapolate that every AUR package is broken
Anyway, patch for minutor:
