FFmpeg/configure
Reimar Döffinger 0956bc9b83 Enable hardcoded tables for ia64 shared builds. 
At least for cross-compilation with Gentoo gcc 4.4.2 it fixes the build errors
due to GPREL 22 being insufficient for the .bss size of > 4 MB without it.
Why these errors do not appear with static builds is unclear, it is not due
to PIC (shared builds with PIC disabled show the same issue).
