Revert "scripts/paxmodule.c: ELF_C_RDWR_MMAP -> ELF_C_RDWR for uclibc compat"
This reverts commit 184b349113189aee285ff9bcb1ca08235a5c29c6.
Using libelf instead of elfutils to gelf_update_phdr() fails. Revert
for now until we figure out what's going on.

scripts/revdep-pax: fixed two bugs

2) print_forward_linkings needs so2filename_mappings to do its job

-Broken reverse dependency rebuilder.

- -i, --ignore Ignore temporary files from previous runs
- -k, --keep-temp Do not delete temporary files on exit

- --library=NAME NAME can be a full path to the library or a basic
- regular expression (man grep)
- -l, --no-ld-path Do not set LD_LIBRARY_PATH
- -P, --no-progress Turn off the progress meter
- -q, --quiet Be less verbose (also passed to emerge command)

-Calls emerge, options after -- are ignored by $APP_NAME

scripts/revdep-paxmark: tool to find mismatched pax markings
This tool will search for binaries which have different pax
markings than the libraries they link against. Since running
processes run with the pax enforcings of the binary, not the
libraries they link against, this utility can be used to locate
such binaries and mark them with the same flags as their libraries.
This code is derived from revdep-rebuild.
