CGMiner build warning: always_inline function might not be inlinable

[stozher]

Code:

sha256_4way.c:54:49: warning: always_inline function might not be inlinable [-Wattributes]
sha256_4way.c:50:48: warning: always_inline function might not be inlinable [-Wattributes]

The '__attribute__((always_inline))' does not strictly imply 'inline'. Newer versions of GCC detect this misuse and issue
the above warning. Including the missing 'inline' resolves the build warning.

Code:

cd /path-to-build-folder
git clone git://github.com/ckolivas/cgminer.git
patch -p0 < git+d4af2d0535.patch
