tools/nolibc: Remove .global _start from the entry point code
[ Upstream commit
1590c59836dace3a20945bad049fe8802c4e6f3f ]
Building with clang yields the following error:
```
<inline asm>:3:1: error: _start changed binding to STB_GLOBAL
.global _start
^
1 error generated.
```
Make sure only specify one between `.global _start` and `.weak _start`.
Remove `.global _start`.
