package/mupdf: disable objcopy

Drop fourth patch and disable objcopy as suggested by upstream in
https://bugs.ghostscript.com/show_bug.cgi?id=704442#c2

This will also fix the following build failure on sparc and xtensa:

    OBJCOPY build/release/resources/fonts/urw/Dingbats.cff.o
/home/buildroot/autobuild/instance-3/output-1/host/opt/ext-toolchain/bin/../lib/gcc/sparc64-buildroot-linux-gnu/9.3.0/../../../../sparc64-buildroot-linux-gnu/bin/ld: --relax and -r may not be used together

While at it, drop MUPDF_DISABLE_OPENGL and use the new MUPDF_MAKE_OPTS
variable

-Subject: [PATCH] Use CC instead of LD for OBJCOPY
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-When cross-compiling for mips targets using Buildroot, using LD for
-partial linking fails in the following way:
-/tmp/instance-1/output-1/host/opt/ext-toolchain/bin/../lib/gcc/mips64el-buildroot-linux-uclibc/8.4.0/../../../../mips64el-buildroot-linux-uclibc/bin/ld: build/release/libmupdf.a(Dingbats.cff.o): ABI is incompatible with that of the selected emulation
-/tmp/instance-1/output-1/host/opt/ext-toolchain/bin/../lib/gcc/mips64el-buildroot-linux-uclibc/8.4.0/../../../../mips64el-buildroot-linux-uclibc/bin/ld: failed to merge target specific data of file build/release/libmupdf.a(Dingbats.cff.o)
-
-To fix it, use CC instead of LD for partial linking.
-
-'nostdlib' has to be added, or it will try to use GCC libraries for
-partial linking and fail with 'cannot find -lgcc_s'.
