  Update LLVMLibCArchitectures.cmake (#112464)

Hi there,

When building llvm-libc on the openEuler system, I encountered an issue
as shown in the image below:

![image](https://github.com/user-attachments/assets/75667de4-5bea-4a95-be28-ed34db0e05b9)

This issue happens because the regular expression used in
`libc/cmake/modules/LLVMLibCArchitectures.cmake`: `string(REGEX MATCH
"Target: [-_a-z0-9.]+[ \r\n]+")` does not handle capital letters
properly in `openEuler`.

To fix this, I modified the regular expression to: `string(REGEX MATCH
"Target: [-_a-zA-Z0-9.]+[ \r\n]+")`. This change makes it compatible
with capital letters.
