libc: prevent execvpe to search for files containing '/'
...
The current implementation always searches for the file in PATH
if it is not an absolute path.
This prevents executing relative paths like ./executable.
As specified by exec(3) the p-family of exec functions only search if
the filename does not contain slash '/' characters.

Clean up cmake files (Part 2)
...
I've kept just one cmake project, in the root directory. The
subdirectories just set up the targets.
The asm compiler is serached just one time, from the root
directory cmake file.
Global compilation flags are set in the root cmake file, and
each subdirectory cmake file sets specific flags if necessary
(e.g., programs need the -u_start specified)
