Original issue's description:
> Fix use of 'sysroot' variable in harfbuzz.gyp
>
> The sysroot variable is set conditionally in common.gypi
> but not at the nesting level required for other conditional
> to depend on it like the one in hardbuzz does.  This means
> that sysroot always appeared to be empty to harfbuzz.gyp,
> and hence the special handling for ARM linux was required.
>
> This change moves the setting of 'sysroot' up one level of
> nesting and defines 'pkg-config' in common.gypi so it can
> be shared.
