This comes from an incompatibility between:
o libc++ (our default C++ standard library), used to build LLVM
from ports (graphics/dri's dependency),
o and libstdc++ (the C++ standard library provided with and used
by GCC), used to build libglapi on i386.
Here, {LLVM headers + libc++ headers} produce different symbols than
{LLVM headers + libstdc++ headers}, because both standard libraries have
incompatible internal representation of standard C++ types. So they are
both "C++ compliant" of course, but they can't be mixed in the same program.
The root of your problem isn't this incompatibility however. Clang is
unable to build Mesa on i386 currently. The workaround was to use GCC
temporarily until Clang is fixed. But it's ineffective, because of the
incompatibility.
