[PATCH 0/6] Remove simplified Meslibc version for TinyCC in RISCV

[Ekaitz Zarraga]

I added Extended Asm support and fixed load/store instruction syntax in both
Bootstrappable TinyCC and upstream TinyCC, so we can remove our simplified
version of Meslibc, that we added because TinyCC's assembler for RISC-V was
weird.

With this set of changes, we remove the riscv64-mes-tcc part of the library, in
favor of the -gcc version, which we can now compile thanks to the improved
TinyCC assembler.

  Revert "build: Add support for TCC in RISC-V."
  Revert "riscv64: Fix arguments of _start function in tcc."
  Revert "riscv64: Simplify assembly constructs not supported by tcc."
  Revert "riscv64: Add support for tcc."
  Revert "lib: Add missing (empty) crt files for RISC-V." partially
  amend! lib: Add setjmp/longjmp for riscv64.
