[gentoo-user] Qt-core-4.5.1 jamboree not optimised for i686

[Mick]

Major build this morning of qt with a lot of blockers.  Having
unmerged a lot of packages to remove the blockers I am now emerging
qt-core.  I noticed this on my screen:

Determining system architecture... (Linux:2.6.29-gentoo-r5:i686)
    32-bit Intel 80x86 (i386)
    'i386' is supported
System architecture: 'i386'
Symbol visibility control enabled.
Symbolic function binding enabled.

This is the Qt/X11 Open Source Edition.

Since I have these in make.conf I would think that a package like qt
would compile optimised code for my architecture, not just i386?

ARCH="x86"
CFLAGS="-O2 -march=pentium3 -fomit-frame-pointer -msse -mmmx -pipe"
MAKEOPTS="-j2"
ACCEPT_KEYWORDS="x86"
CHOST="i686-pc-linux-gnu"
CXXFLAGS="${CFLAGS}"

Just curious.

architecture != cpu type

in this case architecture is things like i386, sparc, mips, arm
