build_visit invocation fails with mpich enabled on LC

[JustinPrivitera]

I figured this would work now that #19600 had been addressed. mpich builds but we fail to build VisIt itself.

build_visit invocation:

./build_visit --makeflags -j24 --mesagl --required --optional --uintah --parallel --mpich

output:

Unable to build or install VisIt. Bailing out.
Error in build process. See /usr/workspace/justin/visit_builds/develop-w-tpls-02_20_25/build_visit_log for more information. If the error is unclear, please include /usr/workspace/justin/visit_builds/develop-w-tpls-02_20_25/build_visit_log and contact the VisIt project via https://visit-help.llnl.gov. You may need to compress the /usr/workspace/justin/visit_builds/develop-w-tpls-02_20_25/build_visit_log using a program like gzip so it will fit within the size limits for attachments.
