This release contains an important TLS fix for ARM along with a few
minor compatibility fixes

1. Make __aeabi_read_tp respect ARM ABI register requirements to
   avoid clobbering register contents during TLS variable use.

2. Use cpu_family instead of cpu in meson config, which is 'more
   correct' when building for a single cpu instead of multilib.

3. Make arm sample interrupt vector work with clang

4. Use __inline instead of inline in published headers to allow
   compiling with -ansi

5. Make 'naked' RISC-V _start function contain only asm
   statements as required by clang (and recommended by gcc).

6. Use -msave-restore in sample RISC-V cross-compile
   configuration. This saves text space.
