devtools: remove useless files from ABI reference

  When building an ABI reference with meson, some static libraries
are built and linked in apps. They are useless and take a lot of space.
Those binaries, and other useless files (examples and doc files)
in the share/ directory, are removed after being installed.

In order to save time when building the ABI reference,
the examples (which are not installed anyway) are not compiled.

The install directory for libraries is not lib/ in all cases.
This breaks the ABI generation for gcc-shared:

DESTDIR=/home/dmarchan/abi/v20.02/build-gcc-shared ninja -C
/home/dmarchan/abi/v20.02/build install >/dev/null
rm: cannot remove
'/home/dmarchan/abi/v20.02/build-gcc-shared/usr/local/lib/*.a': No
such file or directory

$ ls ~/abi/v20.02/build-gcc-shared/usr/local/
bin  include  lib64  share

Is it enough to change lib to lib* ?

I can see only lib/ or lib64/ so ok for me.

If it's using lib, then the .a files could be in /lib/x86_64-linux-gnu/,
rather than in lib directly.  Therefore I think it's better to use find or
similar to remove the .a files from /usr/local/:

find /usr/local -name 'librte*.a' -exec rm -f {}
