[compiler-rt] Fixed build breaking due to #77178 and #86131 (PR #86290)

[Abhin P Jose via llvm-commits]

https://github.com/Abhinkop created https://github.com/llvm/llvm-project/pull/86290

Fixed a small issue of matching pthread signature, which was causing the build to break for the compiler-rt project after adding -Wcast-function-type-mismatch to -Wextra dignostic group.
