Maybe.  Put simply, multilib is the feature of portage that rebuilds
all (most?) libraries twice, once for /lib32, and once for /lib64, to
support 32-bit and 64-bit applications respectively.

Unless you are using a no-multilib sub-profile (which you are not), it
is normal that sandbox will attempt to be built as a 32-bit version.
The problematic point seems to be this test in the sandbox
configuration:

checking for i686-pc-linux-gnu-gcc... no

If that says yes, for example because you have a cross-compiler
installed, then you can have some problems to build the 32-bit version
of sandbox.  Thus why unmerging any cross-compilers or removing any
stale i686-pc-linux-gnu-* links works around the problem.

This bothers me slightly...my output has

[ebuild   R   ] sys-devel/gcc-4.1.1-r1  USE="gcj (-altivec) -bootstrap
-build -doc -fortran -gtk (-hardened) -ip28 -ip32r10k -mudflap
(-multilib) -multislot (-n32) (-n64) -nls -nocxx -objc -objc++
-objc-gc -test -vanilla" 0 kB

Notice the masked use flags multilib/n32/n64...you should be seeing
the same things regardless of the profile.  Maybe this is just due to
differences in portage versions...I'm on 2.1.1 here.
