CMakeDetermineCompilerABI: Strip -pipe from compile flags
When `-pipe` is enabled, GCC passes data among its different executables
using pipes instead of temporary files. This leads to issues when cmake
attempts to infer compiler internals via the `-v` flag as each
executable will print to `stderr` in parallel. Avoid this by stripping
`-pipe` from the compilation flags during compiler inspection.
This extends commit d5895f50c3 (CMakeDetermineCompilerABI: Avoid failing
on warnings with -Werror, 2020-01-30, v3.17.0-rc1~32^2).
