[Buildroot] [PATCH 0 of 2 v4-resend] Add find utility functions / exclude files from strip

[Thomas De Schampheleire]

This patch series adds a few utility functions to Makefile.package.in that
help in composing find commands, and uses these functions to exclude
user-configured files and directories from being stripped in target-finalize.

Thanks to input from Arnout, the find functions are now much simpler and
should be clearly understandable by everyone.

[Buildroot] [PATCH 1 of 2 v4-resend] Makefile.package.in: add utility functions find*clauses and notfirstword

[Thomas De Schampheleire]

This patch adds a few utility functions to Makefile.package.in.

Functions finddirclauses and findfileclauses help in building a find command
that skips a set of directories and performs operations on a set of files.
This pattern can for example be used to keep certain files or directories from
being stripped, or to remove certain files from a package installation.

The notfirstword function is the inverse of the 'firstword' function in make:
it returns all but the first word.

Dammit, frickin people that reorganize the code all the time! ;)

[Buildroot] [PATCH 2 of 2 v4-resend] build: add option to exclude executables/dirs from being stripped

[Thomas De Schampheleire]

Sometimes it may be desirable to keep debug symbols for some binaries and
libraries on the target. This commit introduces the config option
BR2_STRIP_EXCLUDE_FILES, which is interpreted as a list of such binaries
and libraries, and the option BR2_STRIP_EXCLUDE_DIRS, which indicates
directories excluded from stripping entirely.
These exclusions are passed to the find command in the target-finalize step.
