clang.patch

media-gfx/sam2p-0.49.4_p20190718-r1 fails to configure when built with clang and hardened flags are set.

Steps to reproduce:
    1. Set LDFLAGS to "-Wl,-O1 -Wl,--as-needed -fuse-ld=lld -rtlib=compiler-rt -unwindlib=libunwind -pie"
    2. Set CFLAGS to "-march=native -O2 -pipe -fPIC -fstack-protector-strong -D_FORTIFY_SOURCE=2"
    3. Set CXXFLAGS to "-march=native -O2 -pipe -fPIC -fstack-protector-strong -D_FORTIFY_SOURCE=2"
    4. Attempt to emerge media-gfx/sam2p-0.49.4_p20190718-r1
    5. Observe build failure

Excepted results:
    sam2p-0.49.4_p20190718-r1 configures successfully

Actual results:
    build fails with error:
        checking whether we are cross compiling... configure: error: in `/var/tmp/portage/media-gfx/sam2p-0.49.4_p20190718-r1/work/sam2p-b953f63307c4a83fa4615a4863e3fb250205cd98'
    config.log error:
        configure:2736: checking whether we are cross compiling
        configure:2744: clang++ -o conftest    -Wl,-O1 -Wl,--as-needed -fuse-ld=lld -rtlib=compiler-rt -unwindlib=libunwind -pie conftest.cpp  >&5
        ld.lld: error: can't create dynamic relocation R_X86_64_64 against local symbol in readonly segment; recompile object files with -fPIC
