# HG changeset patch # User Michael Hope <michael.hope@linaro.org> # Date 1317777591 -46800 # Node ID 415f1de11ddcc321d5e6cf2f7cd058973045507f # Parent f051032a1070eda28557dd738c35446b44787217 Support extra host compiler flags. Allow the user to configure extra flags to pass to the host compiler at build time. Applies to both C and C++. Useful on Ubuntu to turn off the stack protector and fortify defaults so the program stands a better chance of running on other distros.
