Have you checked yasm's Makefile?

# grep -ic flags yasm-1.3.0.ebuild
0

However, emerge --info yasm shows me that only -march -O2 -pipe make it
through. Where is the code that strips the others?

There's mentions of CFLAGS in there but I don't have the knowledge to
understand it. Is there a way I can tweak what the makefiles have done? I
tried adding;

append-flags <flag>

in the src_configure() section, but <flag> doesnt get added, according to
emerge --info

I would strongly advise against that, just on principle.

yasm is an assembler, and as such it's right at the bottom of the stack.
It's not unreasonable for such a package to use different FLAGS etc as
it's not a userland app. It's an app that builds things you use to build
a userland.

I would recommend you touch base with the package maintainer for answers.

btw, why is this situation a problem? Is something wrong with the yasm
portage builds you?

I'm trying to avoid a reinstall. With profile 17, i found many packages
required -fPIC to build (probably due to some mucking around i've done with
hardened, and/or gentoo devs earlier force on of PIE in gcc that they later
backed out.). yasm build is failing and saying try -fPIC.
