porting new arch

[Shinpei Kato]

Hello,

I've been porting new arch to GCC for a last month with refering to MIPS arch.
Coding has been almost done and now in debugging. I managed to solve several problems, however, now I'm facing unclear one.
I got the following error messages from GCC during make.

libbackend.a(gtype-desc.o)(.text+0x568): In function`gt_gcc_mx_function':
/.../build-gcc/gcc/gtype-desc.c:259: undefined reference to `gt_ggc_mx_machine_function'
collect2: ld returned 1 exit status
make[1]: *** [cc1] Error 1

It seems that there is no gt_ggc_mx_machine_function() in gt_ggc_mx_function. Besides gtype-desc.c is generated automatically during make.
How could I solve this problem?
