ldso: Add implementation of ld.so standalone execution
The dynamic linker can be run either indirectly through running some
dynamically linked program or library (in which case no command line options
to the dynamic linker can be passed and, in the ELF case, the dynamic linker
which is stored in the .interp section of the program is executed)
or directly by running:
/lib/ld-uClibc.so.* [OPTIONS] [PROGRAM [ARGUMENTS]]
Stand-alone execution is a prerequisite for adding prelink capabilities
to uClibc dynamic linker, as well useful for testing an updated version
of the dynamic linker without breaking the whole system.
Currently supported option:
--library-path PATH use given PATH instead of content of the environment
variable LD_LIBRARY_PATH
(Mandatory for prelinking)
Not supported options:
--list list all dependencies and how they are resolved
--verify verify that given object really is a dynamically linked
object we can handle
--inhibit-rpath LIST ignore RUNPATH and RPATH information in object names
in LIST
This feature can be enabled by setting LDSO_STANDALONE_SUPPORT=y
