stage1: Add missing bitcast when rendering var ptr
...
Some types require this extra bitcast, eg. structs or unions with extra
padding fields inserted by the compiler.
Fixes #7250

std: Avoid deadlock in the signal handler
...
stderr_mutex may still be held when we reach the signal handler, grab
our own stderr handle to print the error messages and avoid deadlocking.

restore sonames by default when using zig cli
...
Before this commit, the branch regressed this case:
zig build-lib foo.zig -dynamic
readelf -d libfoo.so
x000000000000000e (SONAME) Library soname: [libfoo.so]
Now it works again, but it preserves the property that using `zig cc`
has the SONAME off by default to match C compilers.

stage2 elf: make -soname an opt-in and not opt-out
...
As discussed with LemonBoy, it makes more sense to have the `-soname`
an opt-in option rather than opt-out, which is especially true if
we are to align `zig cc` with `cc` to a greater degree.

Fix fork() on Linux/sparc64
...
fork() on Linux/sparc64 seems to return its result in two registers,
with %o0 always holding the current process' PID, and the parent/child
status returned in %o1. Add some glue code to convert those into
the libc-style return value.
