OK.  Don't do that.  Try just

   make EMBED=....../IPXE.script bin/808610de.rom

and it should automatically use the correct toolchain and build a 32-bit 
binary (which _is_ what you want, since you've asked for 
bin/808610de.rom rather than bin-x86_64-pcbios/808610de.rom).

In the unlikely even that you need to specify a custom toolchain (i.e. 
if your default "gcc" binary is not an x86 compiler), then you can 
specify an explicit toolchain prefix using CROSS:

   make CROSS=x86_64-pc-linux-gnu- \
        EMBED=....../IPXE.script \
        bin/808610de.rom
