[SCM] libav/experimental: FLAT objects cannot have multiple sections, so using the L1 attributes breaks linking. The FDPIC relocs also break for any other format. Thus check the compiler environment and select the appropriate sections/relocs. patch by Mike Frysinger, vapier.adi a gmail d com

commit d2a4ecafbba2a1a5895c6c3e2e6781f9751a681d

    FLAT objects cannot have multiple sections, so using the L1 attributes breaks
    linking. The FDPIC relocs also break for any other format. Thus check the
    compiler environment and select the appropriate sections/relocs.
