the ebuild appends "-m64" to compiler flags whereas a "-m32" is already given...

Thanks for the report, let's see...

It's strange that you got 1.9.2 in, as the Jam files did not change for this step (Jambase file, line 979):
    # Make things work on 64 bit Linux
    # Because HOSTTYPE is not normally exported, check the uname() result
    if ! $(HOSTTYPE) {
        HOSTTYPE = $(JAMUNAME[1]) ;
    }

    if $(HOSTTYPE) = x86_64
     || $(HOSTTYPE) = x86_64-linux
     || $(HOSTTYPE) = amd64 {
        ECHO "We're on a 64 bit host" ;
        HOST64     = true ;
        CFLAGS     += -m64 ;
        C++FLAGS   += -m64 ;
    }

Or did you have a 32bit kernel before? As it's apparently using uname output

Anyway from looking at the code (jam is not yummy I can tell you), setting HOSTTYPE on the jam line in the ebuild should do the trick:
HOSTTYPE=${CHOST/-*} jam ...

Marking test request until confirmation fix from comment 1 helps
