get_musl_loader_arch returns the arch part of ldso for musl, this is
used in get_musl_loader() as well as independently usable, which is
needed for multilib support in musl. Musl stores all ldso in /lib
be it multilib or not, therefore do not use base_libdir instead directly
use /lib

Fix the naming of the loader on armhf to match what glibc expects:
#define GLIBC_DYNAMIC_LINKER_SOFT_FLOAT SYSTEMLIBS_DIR "ld-linux.so.3"
#define GLIBC_DYNAMIC_LINKER_HARD_FLOAT SYSTEMLIBS_DIR "ld-linux-armhf.so.3"

this makes it possible to use this for musl where we are trying to
create a glibc compat package

We could do with one decent general purpose python function to query the
path to the dynamic loader. Convert the shell code into python.
Also correct baremetal to return "None", not musl loaders.

Current linuxloader.bbclass does not support musl libc ldso, so add it
in.
After changing, now the linuxloader function will call a subfunction
according to which virtual/libc is being used, glibc or musl, the
linuxloader_musl function is made on top of the LDSO macro defined
in musl source, by mapping related OE variables to it.
Change tested on following machines:
"genericx86"
"genericx86-64"
"beaglebone"
"qemumips64"
"qemuarm64"
"mpc8315e-rdb"
"edgerouter"
"qemumips"
"kc705-microblazeel" - meta-xilinx
"qemuppc"

[YOCTO #10389]
Use a glob (*) to match all mips (not previously matched). This will ensure
that the linuxloader is properly returned for mips, mipsel, mips64,
mips64el and their n32 variants.
See: https://sourceware.org/glibc/wiki/ABIList#mips for the official list
of loaders.

Add support for MIPS Release 6 ISA. The loader is located at a
new place for multiarch.
For more details, check https://wiki.debian.org/Multiarch
and https://sourceware.org/glibc/wiki/ABIList#mips

Prelinking on x86-64 wasn't working out the box as it uses /lib and
not /lib64 for libs. Prelink was refusing to link as the dynamic loader
didn't match its idea of the right path. Passing in the --dyanmic-linker
option avoids this.
We can share code from image-mklibs so abstract that into a new class,
linuxloader.bbclass.
This does break prelinking of multilib images, I've opened a bug so we
can loop back and fix that problem, the code would need to iterate the
dynamic loaders (and setup ld.so.conf files for it).
