Comment (by lukaso):

 Yes, this works fine.

 If you look at `cmake_bootstrap.log` you'll see that the clang++
 executable is missing from the command.

 This is a good run on arm64 (not the same test, but you get the idea):

 {{{
 Try: /usr/bin/clang++
 Line: /usr/bin/clang++ -pipe -Os
 -isysroot/Library/Developer/CommandLineTools/SDKs/MacOSX11.3.sdk -arch
 arm64 -std=gnu++14  -DTEST_KWSYS_CXX_HAS_EXT_STDIO_FILEBUF_H

 bootstrap/work/cmake-3.9.6/Source/kwsys/kwsysPlatformTestsCXX.cxx -o
 cmake_bootstrap_41862_test
 }}}

 And this is a bad run on rosetta x86_64 (note the `Try:` line).

 {{{
 Try:
 Line:  -pipe -Os
 -isysroot/Library/Developer/CommandLineTools/SDKs/MacOSX10.13.sdk -arch
 x86_64 -qlanglvl=extended -DTEST1 cmake_bootstrap_18180_test.cxx -o
 cmake_bootstrap_18180_test
 }}}
