287: Fix common uses of INSERT AFTER with .bss and .text r=adamgreig a=mattico Fixes #267 Fixes #266 This fixes two related issues. 1. Named sections are often inserted after `.bss` or `.text` in order to have them handled as if they were part of that section. Defining the start/end symbols outside of the section allows this to work. 2. Uninitialized C statics will end up as common symbols which end up in the COMMON input section. If this section is orphaned, it will likely end up placed after `.bss`. C code often expects these statics to be zero initialized. The first change would cause these symbols to be placed before `__ebss` so they will get zeroed by the reset handler. Explicitly placing the common symbols into `.bss` ensures this happens. Users who want uninitialized symbols should use the `.uninit` section. See rust-embedded/cortex-m-rt#287 (comment) Co-authored-by: Matt Ickstadt <mattico8@gmail.com>

https://docs.rs/panic-semihosting/0.5.4/panic_semihosting/ is empty, despite there being documentation on the crate.
Caused by
#![cfg(all(target_arch = "arm", target_os = "none"))].The fix is to tell docs.rs to use an embedded ARM target (see https://docs.rs/about/metadata).
