Rich Felker 5baf2d92d3 ldso: use __ehdr_start if available to locate its own ELF headers 
previously, the relative load address was used as the address at which
to find the ELF headers. this only works if two conditions are met:
ldso is linked to start at a virtual address of 0, and the linker is
cooperative and includes the main ELF headers in a loadable segment.

while in practice these are always met, modern linkers provide a
__ehdr_start symbol pointing to the ELF headers, and can in principle
use the reference to this symbol as an indication that they need to be
mapped in a segment. this also should make it possible to link for a
different starting virtual address, if that's ever desirable.

    musl libc

musl, pronounced like the word "mussel", is an MIT-licensed
implementation of the standard C library targetting the Linux syscall
API, suitable for use in a wide range of deployment environments. musl
offers efficient static and dynamic linking support, lightweight code
and low runtime overhead, strong fail-safe guarantees under correct
usage, and correctness in the sense of standards conformance and
safety. musl is built on the principle that these goals are best
achieved through simple code that is easy to understand and maintain.

The 1.1 release series for musl features coverage for all interfaces
defined in ISO C99 and POSIX 2008 base, along with a number of
non-standardized interfaces for compatibility with Linux, BSD, and
glibc functionality.

For basic installation instructions, see the included INSTALL file.
Information on full musl-targeted compiler toolchains, system
bootstrapping, and Linux distributions built on musl can be found on
the project website:
