toolchain-shar-relocate.sh: make it faster
Make the extrating faster by: * Merge the two heavy "for .. find" loops into one * Move the commands out of for loop rather than inside, this can reduce the forking amount. As a result, when install: * buildtools-nativesdk-standalone: 14s -> 7s (50% saved) * core-image-minimal-core2-64-toolchain: 56s -> 47s (17% saved) [YOCTO #8404] Signed-off-by: Robert Yang <liezhi.yang@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
