[Bug target/44793] New: Code generated references undefined symbol

[joel at gcc dot gnu dot org]

This was spotted on powerpc-rtems but likely impacts more targets.  It is
triggered by -Os. I will attach the preprocessed file.

powerpc-rtems4.11-gcc (GCC) 4.5.0 20100414 (RTEMS
gcc-4.5.0-10.fc12/newlib-1.18.0-10.fc12)

$ powerpc-rtems4.11-gcc -mcpu=603e -Os -S j.c
$ grep _rest j.s
        b _restgpr_31_x
$ powerpc-rtems4.11-gcc -mcpu=603e -O0 -S j.c
$ grep _rest j.s
$ powerpc-rtems4.11-gcc -mcpu=603e -O1 -S j.c
$ grep _rest j.s
$ powerpc-rtems4.11-gcc -mcpu=603e -O2 -S j.c
$ grep _rest j.s
