[PATCH] ARM: LLVMLinux: Change "extern inline" to "gnu_inline" in ARM ftrace.h

[behanw at converseincode.com]

From: Mark Charlebois <charlebm at gmail.com>

With compilers which follow the C99 standard (like modern versions of gcc and
clang), "extern inline" does the wrong thing (emits code for an externally
linkable version of the inline function). In this case using the gnu_inline
attribute makes inline do the right thing on gcc and on clang.
