modular policy allows for customization to local policy.  You can look 
at policy generated by audit2allow -M  to see this.  Most of the 
problems you are talking about are from libraries requesting more privs 
then they require execmod.  You can change the file context on those 
files to tell selinux to allow the access.   chcon -t textrel_shlib_t 

Explains the risks of the exec* accesses.

Any time you see this, it should be reported as a problem with SELinux 
policy but also reported back to the package maintainer, as they might 
have a problem with their library.
