Custom bionic-based linker

What works

• Loading some dynamic libraries from static binary linked with same libc
• Loading some dynamic binaries and hook it to host libc
• Hooking exported symbols
• Generating stubs for undefined symbols
• Ignoring missing libraries
• Ignoring library versions

What does not work

• Loading glibc itself (use linked libc instead)
• Loading static binaries (is it possible?)
• Complex multi-thread libraries and applications

Useful scripts

• Use ./gen.sh [/path/to/lib1] [path/to/lib2] to generate wrappers to host libraries. syms.txt will contain accumulated symbols list

• Use build.sh to build libdl-compatible loader

• Use build-main.sh to build linker-like loader

Enviroment variables

• HYBRIS_LINKER_DEBUG=N

• CUSTOM_LD_PRELOAD

• CUSTOM_LD_LIBRARY_PATH

• Other libhybris envs
