21 In the current world of gentoo-x86 it is the rule. But what will you do
22 once Sun Studio becomes open source, and you want to allow people that
23 like to have better performance to use it? What if Gentoo Prefix ever
24 gets merged back into gentoo-x86?
25
26 How can you easily revert it in a profile? Using strip-ldflags alike?
27 That feels nasty to me. If it is trivial to remove it again,
28 considering there may be more in LDFLAGS, then it is less of a problem
29 to me. Maybe there is such a way, and I just missed it.
