Comment (by ryandesign):

 The bazel executable contains embedded zip-compressed data. It's in there.

 With the bazel-3.7 @3.7.2_1 binary for Catalina:

 {{{
 $ cd /tmp
 $ unzip /opt/local/bin/bazel-3.7
 $ grep -C 2 'binary_name == "wrapped_clang"'
 embedded_tools/tools/osx/crosstool/wrapped_clang.cc
   if (binary_name == "wrapped_clang_pp") {
     tool_name = "clang++";
   } else if (binary_name == "wrapped_clang") {
     tool_name = "clang";
   } else {
 }}}

 Rebuilding it from source:

 {{{
 $ unzip /opt/local/bin/bazel-3.7
 $ grep -C 2 'binary_name == "wrapped_clang"'
 embedded_tools/tools/osx/crosstool/wrapped_clang.cc
   if (binary_name == "wrapped_clang_pp") {
     tool_name = "/opt/local/var/macports/build
 /_Users_rschmidt_macports_macports-ports-ryandesign-
 fork_devel_bazel/bazel-3.7/work/bazelwrap/cxx";
   } else if (binary_name == "wrapped_clang") {
     tool_name = "/opt/local/var/macports/build
 /_Users_rschmidt_macports_macports-ports-ryandesign-
 fork_devel_bazel/bazel-3.7/work/bazelwrap/cc";
   } else {
 }}}

 The bazel-3.7 binary for macOS 10.15 was produced in April 2021 while the
 binary for macOS 12 x86_64 was made in November 2021.

 There was a flurry of changes to the bazel 1.0 portgroup, starting with
 [5d9765ddd7d0c8f16d25beeca7be37fd74c42f1d/macports-ports] in early May
 2021, that introduced the code that modified wrapped_clang.cc.

 Since these changes to the bazel 1.0 portgroup have an effect on the files
 that get installed with bazel-3.7 (and maybe other bazel versions), the
 revisions of the bazel ports should be increased, either now or better yet
 after you've made further changes to mitigate the problem.
