[Mans Rullgard]

ffmpeg | branch: master | Mans Rullgard <mans at mansr.com> | Sun Feb 27 23:34:38 2011 +0000| [42ccd2fcf834db379834d39b4012cbe18152dfe4] | committer: Michael Niedermayer

Use --sysroot flag for clang

Although not documented, clang does support the --sysroot flag, and it
does the right thing.  Use this flag intead of -isysroot which only
applies to header file searches, not the linker.
