[v1,2/2] devtools: use absolute path for the build directory

From: Phil Yang <phil.yang@arm.com>

To make the code easier to maintain, use the absolute path for the
default build_dir to avoid repeatedly calling of readlink.

Hi, Bruce

Sorry to disturb you again. Would you please help review the second patch
of this series? Thanks very much.

It means that all uses of builds_dir will get the absolute path.
It may have consequences on meson configuration,
and will make outputs and logs longer.

I'm not sure this change is desirable.

Hi, Thomas

Thanks for your reviewing.

I agree with your comment. 
As your concern, this patch is simple but may have some negative effects.
Thus I will drop it from series in the next version.

Best Regards
