This patch breaks the build of flang when quad math support is enabled (https://github.com/llvm/llvm-project/pull/81971).   Quad math support is off by default (why no buildbot tripper over this), and can be enabled by setting the following cmake variable:

-DFLANG_RUNTIME_F128_MATH_LIB=libquadmath

With this patch applied, all libquadmath symbols cannot be found during the build: cosq, acoshq, ...
