I and some other people have the same problem on newsmips and sgimips.
crunchgen(1) generate a makefile which uses objcopy(1) to hide global
symbols rather than (old) crunchide(1) if NEW_TOOLCHAIN is defined.
But as noted in usr.bin/crunch/crunchide/exec_elf32.c:
* This function 'hides' (some of) ELF executable file's symbols.
* It hides them by renaming them to "_$$hide$$ <filename> <symbolname>".
* Symbols in the global keep list, or which are marked as being undefined,
* are left alone.
* An old version of this code shuffled various tables around, turning
* global symbols to be hidden into local symbols. That lost on the
* mips, because CALL16 relocs must reference global symbols, and, if
* those symbols were being hidden, they were no longer global.
it causes problem on MIPS to change global symbols into local ones
to hide them. I guess we have to rename them and keep them global
on some architectures (i.e. mips).
Maybe we have to have BFD'fied crunchide(1), which already exists
in pkgsrc/cross/bfd-crunchide, instead of simple objcopy(1).
