Apparently, the definition of the FORCE_INLINE macro in lz4.c has
been broken in https://github.com/lz4/lz4/commit/258a5e7fa4482548
In its current shape the macro uses the C99 'inline' keyword even when
compiling in C89 or C90 modes.

  (FORCE_INLINE): Revert this macro to its state before 258a5e7fa4482548.
