[Clc-crux64] to -fPIC or not to -fPIC

All right, I'm a little bothered by my current build, w/out -fPIC in the
CFLAGS/CXXFLAGS. I've had to recompile so many packages after the fact,
when another package comes and tells me to recompile so-an-so lib
w/-fPIC, that I'm considering putting it back in the pkgmk.conf and
1. Don't have to worry about adding "export CFLAGS="$CFLAGS -fPIC" to
every other Pkgfile (seems to be required with a boatload of the
multimedia apps I've been compiling)
2. Isn't position independent code a Good Thing(tm)? Not being schooled
in the black arts of c programming, I have a hard time explaining to
myself why, but I think it has to do with where objects can be loaded in
a system's address space...
1. Ummm... Gentoo-wisdom says not to add it to CFLAGS/CXXFLAGS. Anyone
"PIC objects are usually slightly larger and slower at runtime than the
equivalent non-PIC object". Slightly larger doesn't bother me much --
probably few of us running x86_64 processors w/tight disk space anyway,
right? Slightly slower -- well, although my amd64 can probably afford
slightly slower, I would like to squeeze every ounce of performance I
can out of this box...
So, I'm taking recommendations here. Does anyone care enough one way or
the other to convince me of their position?
