commit 89f7c89e882dc54545c9f50c049bf1085643b431
Author: Domino Valdano <dvald...@pivotal.io>
AuthorDate: Thu Feb 25 21:54:46 2021 -0500
Set optimization flags based on build type, limit to max -O1
Apparently, the build-specific flags automatically get appended
to the generic flags... so we can't put them in the generic list
of flags because the build-specific ones take precedence
( -O0 -O3 is the same as -O3 )
