[llvm] [Hexagon][test] Fix more tests on linux-musl (PR #66785)

[Natanael Copa via llvm-commits]

https://github.com/ncopa created https://github.com/llvm/llvm-project/pull/66785

-march=hexagon uses the default target triple and changes the arch part of hexagon. On linux-musl, this essentially becomes hexagon-unknown-linux-musl which has different code generation. Use -mtriple instead.

Subject: [PATCH] [Hexagon][test] Fix more tests on linux-musl

-march=hexagon uses the default target triple and changes the arch part of
hexagon. On linux-musl, this essentially becomes hexagon-unknown-linux-musl
which has different code generation. Use -mtriple instead.
