[OMPI users] Build error On macOS

[Sahir Butt via users]

I am trying to build openmpi-4.0.3 with gcc 11 on macOS. I ran following to 
configure:

../configure --prefix=/path-to/opt/openmpi-4.0.3 
--with-wrapper-ldflags="-Wl,-search_paths_first”

I keep getting following error:

checking for objdump... objdump
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/objdump:
 error: 'conftest.o': Invalid/Unsupported object file format.

Any ideas?
