Packages/uClibc/patches/30 dlsym-verbose-dev.diff

• When DEBUG=yes in config/options, allows creation of the file

/dlsym.log which contains all the symbols from libraries that are accessed via dlopen()/dlsym()/dlclose() procedure (and so the symbols are not directly accessible from the resulting binary).

Intended use is to create a file which can be sort|uniq'd into an alphabetically-ordered list, so that libstrip can be used on those libraries that are used by programs that use dlsym(), without stripping out required symbols.
