Dear Jakub,
I find your comment misleading for the --with-specs option.
It sets CONFIGURE_SPECS macro, which is used in gcc.c as
static const char *const driver_self_specs[] = {
"%{fdump-final-insns:-fdump-final-insns=.} %<fdump-final-insns",
DRIVER_SELF_SPECS, CONFIGURE_SPECS, GOMP_SELF_SPECS, GTM_SELF_SPECS
};
so it is a list of specs for the driver *itself*, should not be used to specify
link spec.
If you mean passing --with-specs="-Wl,-dynamic-linker=/whatever/ld.so" to
configure, it is broken in multilib cases.
Therefore we lack of a convenient way to specify a default alternative location
of the dynamic linker.
