To ask for sorting output, initially by name.
This is needed in 'btfdiff' to diff the output of 'pahole -F dwarf
--jobs N', where N threads will go on consuming DWARF compile units and
and pretty printing them, producing a non deterministic output.
So we need to sort the output for both BTF and DWARF, and then diff
them.
This is still not enough for some cases where different types have the
same name, things like "usb_priv" that exists in multiple DWARF compile
units, the first processed is "winning", i.e. being the only one
considered.
I have to look how BTF handles this to adopt a similar algorithm and
keep btfdiff usable as a regression test for the BTF and DWARF loader
and the BTF encoder.

Build instructions:
1. install cmake
2. mkdir build
3. cd build
4. cmake -D__LIB=lib ..
5. make install
cmake Options:
-DBUILD_SHARED_LIBS
By default SHARED libraries are created and applications are linked to it.
Use -DBUILD_SHARED_LIBS=OFF while invoking cmake to create STATIC libraries
and link applications to it.
Ex. cmake -D__LIB=lib -DBUILD_SHARED_LIBS=OFF ..
-DCMAKE_INSTALL_PREFIX
Default is to install to /usr/local, use -DCMAKE_INSTALL_PREFIX=
when invoking cmake to specify another install location.
