[FFmpeg-devel] [PATCH] configure: detect 64-bit generic platforms

[Rémi Denis-Courmont]

Currently, any unrecognised platform is treated as 32-bit. This should
detect *most* 64-bit platforms, namely LP64 and LLP64 ones.
Unfortunately this will not work for ILP32 ABIs on 64-bit ISAs, but
still better than nothing.
