For binaries, yes.

For sources of tests, I do not see any confusion if they would be grouped
in a separate directory, e.g. src/<subdir>/<app>/tests.

Maybe. Given that there are 43 man pages and 15 .c files in libpthread,
it would be enough to move out man pages (at least for me). For mutex
there would be only one pthread_mutex.c module. :)

Sounds reasonable. I do not see a problem to have foo_test.c and other
files in the same directory if there are only few of them (e.g. foo.c,
foo_test.c and Makefile). Concern is to not mix up many .c and _test.c
files into a single massive directory.
