Issue

The libc is searched through the complete filesystem. This can take a very long time and does not support analysis of cross plattform analysis. For example one wants to analyse libraries for Android on a Linux PC. The Linux PC uses glibc on x64 and Android another libc on ARM.

The optional parameter libcfile allows to specify a libc.so file or a search path, where libc should be found. If libc is not found, the search is done through the complete filesystem.
