5416c204a9 Always have math functions but with weak linking attribute if we can 
This is a replacement for https://github.com/rust-lang/libm/pull/290

This fixes crashes during compilations for targets that don't have math
symbols by default.

So, we will provide them libm symbols, but mark it as `weak` (if its
supported), so that the linker will choose the system builtin functions,
since those are sometimes more optimized.
If the linker couldn't find those, it will go with `libm`
implementation.

f23a83c53c Add __chkstk on i686-pc-windows-gnu. 
libLLVMSupport.a(DynamicLibrary.cpp.obj) references ___chkstk, which is
an alias of __alloca in libgcc.  This crate provided __alloca, but
libgcc's implementation was also pulled in by the linker due to the
reference to ___chkstk, causing a multiple definition linker error.
Providing that symbol here prevents that.

Fixes #585

2f8b08f9e3 Remove 80-bit builtins entirely 
It turns out that these also don't build on x86 + MSVC. Rather
than fixing up the condition, I'm just deleting them entirely.
As far as I know, Rust does not support 80-bit floats and has
no plan to support them, so we shouldn't need them.

e898296fd9 build: Allow building C compiler-rt fallbacks for RISC-V 
Now that https://github.com/rust-lang/rust/pull/117654 has been merged
the rust-lang/rust distribution containers contain RISC-V C compilers.

This means that we can now enable the "c" feature fallback.

c2c4c8e146 fix: Add (even more) #[avr_skip] for floats 
Tale as old as the world - there's an ABI mismatch:
https://github.com/rust-lang/compiler-builtins/pull/527

Fortunately, newest GCCs (from v11, it seems) actually provide most of
those intrinsics (even for f64!), so that's pretty cool.

(the only intrinsics not provided by GCC are `__powisf2` & `__powidf2`,
but our codegen for AVR doesn't emit those anyway.)

Fixes https://github.com/rust-lang/rust/issues/118079.

to detecting underflow/overflow. The functions now match the behavior of the
MUSL implementations these were based on.
