Since IAMCU tests clear all scratch integer registers with:

  asm __volatile__ ("xor %%eax, %%eax\n\t" \
                    "xor %%edx, %%edx\n\t" \
                    "xor %%ecx, %%ecx\n\t" \
                    ::: "eax", "edx", "ecx");

PIC register may be trashed between setting PIC register and using it.
This patch compiles AMCU tests with -fno-pie -no-pie.

	PR target/67110

    There is no need to make type descriptors for named types when there
    are errors during package compilation.  Particularly, if the error in
    package compilation is from a malformed named type, there is no
    guarantee a type descriptor can be created.
    
    Fixes golang/go#11560.
