Subject: android: Update toolchain build to handle single ABI
X-Git-Tag: upstream/1.1.92~745
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f220a620607ab5b580933df82a70bbf7d4aa2abf;p=platform%2Fupstream%2FVulkan-Tools.git

android: Update toolchain build to handle single ABI

This reduces local arm32 toolchain build from 3m30s to 42s.

Also update Travis-CI config to use the new flag, greatly reducing
Android build time.
