Picolibc version 1.5

1. Make picolibc more compatible with C++ compilers.

2. Add GCC specs file and linker script for building C++ applications
   with G++ that enable exception handling by linking in call stack
   information.

3. A few clang build fixes, including libm exception generation

4. Nano malloc fixes, especially for 'unusual' arguments

5. Merge in newlib 4.1.0 code

6. More libm exception/errno/infinity fixes, mostly in the gamma funcs.

7. Add tests for all semihost v2.0 functions.

8. A few RISC-V assembly fixes and new libm code.

9. Build fixes to reliably replace generic code with
   architecture-specific implementations.

With a patch which is pending for GCC 11, we'll be able to build C++
applications that use picolibc with exceptions and iostream.
