Why qt3 build with linux-g++ , hot with linux-g++-64?

My Qt is 64-bit:
$ file /usr/qt/3/lib/libqt-mt.so.3.3.6
/usr/qt/3/lib/libqt-mt.so.3.3.6: ELF 64-bit LSB shared object, x86-64, 
version 1 (SYSV), stripped

Perhaps you've configured your system incorrectly, but using an x86 install 
CD (and handbook) rather than an amd64 install CD (and handbook).

ghm.... as things turnedout my Qt  is 64-bit too...:
sheridan@amd /usr $ file /usr/qt/3/lib/libqt-mt.so.3.3.6 
/usr/qt/3/lib/libqt-mt.so.3.3.6: ELF 64-bit LSB shared object, AMD x86-64, version 1 (SYSV), stripped

but why build profile is  linux-g++?

I'm not the Qt maintainer, so this is simply a guess, but without
investigating to deeply, probably because portage isn't setup to handle
full dual-arch, that is, with a few toolchain exceptions (glibc, gcc,
binutils, portage's sandbox) it handles 64-bit only, on amd64.  If you
want 32-bit, you either emerge the precompiled 32-bit binaries, or use a
32-bit chroot, thus keeping the 32-bit portage database separate from the
main system (64-bit) portage database.  Since portage doesn't have to
worry about keeping the two separate, the Qt build can use the generic
linux-g++, instead of having to track 64-bit separately from 32-bit as it
would if they were built and delivered together in the same package.
