Bug#1142174: sh4-linux-gnu-gcc does not produce big-endian binaries

Package: gcc-15-sh4-linux-gnu
Version: 15.3.0-1cross1
Severity: normal

When trying to build an sh4eb binary, there's a failure at the link stage:

 sh4-linux-gnu-gcc -mb vdso.S [other options]
 ...
 sh4-linux-gnu-ld.bfd: unrecognised emulation mode: shelf_linux
 Supported emulations: shlelf_linux shlelf_fd

>From the specs:

 *link_emul_prefix:
 sh%{!mb:l}elf

I dunno if this is supposed to be valid or not, and whenever this is a
gcc bug (specs file) or missing support in binutils.

as gets --big option correctly.

Also, using

 sh4-linux-gnu-gcc -Wl,-EB -Wa,--big vdso.S

produces a binary, but I dunno (yet) if it is the right one or not.

This is needed for qemu, as it now ships vdso for sh4eb (in assembly
form, so it does not need anything extra) which has to be compiled.

Thanks,
