32 bit and 64 bit are completely different architectures - you can't
mix and match them in one executable.
The python solution is to use distutils and build a setup.py then you
can compile for each platform easily.

I don't think so.
You can choose which you compile with. On 32 bit you'll compile 32
bit by default. If you want 64 bit choose -m64, eg
echo <<'#END' >z.c
#include <stdio.h>
int main(void)
{
printf("Hello\n");
return 0;
}
#END
gcc -c -m32 -o z32.o z.c
gcc -c -m64 -o z64.o z.c
file z*.o
gives
z32.o: ELF 32-bit LSB relocatable, Intel 80386, version 1 (SYSV), not stripped
z64.o: ELF 64-bit LSB relocatable, AMD x86-64, version 1 (SYSV), not stripped
