Description of the problem / feature request:
Bazel builds using rules_cc on recent (Ventura, Sonoma) MacOS fail with
compiling lib/findprog-in.c...
./lib/findprog-in.c:137:25: error: implicit declaration of function 'eaccess' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
if (eaccess (progpathname, X_OK) == 0)
^
./lib/findprog-in.c:137:25: note: did you mean 'access'?
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/unistd.h:431:6: note: 'access' declared here
int access(const char *, int);

./lib/findprog-in.c:211:21: error: implicit declaration of function 'eaccess' is invalid in C99 [-Werror,-Wimplicit-function-declaration]

^

The root cause of this issue was that bazelbuild/bazel#16414 was not merged to rules_cc, but only to rules_llvm and apple_support. Which removed the culprit -undefined dynamic_lookup.
This issue gives more insight in the problem:

What operating system are you running Bazel on?
What's the output of bazel info release?
release 6.0.0- (@Non-Git)
If bazel info release returns "development version" or "(@Non-Git)", tell us how you built Bazel.
Conda forge
What version of rules_cc do you use? Can you paste the workspace rule used to fetch rules_cc? What other relevant dependencies does your project have?
