[PATCH for-4.22(?) 0/2] tools: Use the system liblz4 package

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

Switch to using the system liblz4.

This brings libxenguest's lz4 decompression in line all the others, rather
than using the unsafe decompressor from Xen (itself a port of Linux's unsafe
decompressor).

Andrew Cooper (2):
  tools/configure: Detect the presence of liblz4
  tools/libs/guest: Use the system liblz4 in the bzimage loader
