lz4: Fix broken builds when pkg-config is not present but system library is
In commit f91e4863bc1382 we fixed an issue where LZ4_LIBS could be
overwritten in some situations. But on systems where lz4 is installed on
the system but is lacking pkg-config information, the linker will not know
about the lz4 library when completing the build.
This fixes the issue by explicitly setting LZ4_LIBS to contain -llz4
if pkg-config test was run and failed verifying the installed lz4 version
number. This also ensures that LZ4_LIBS will not be overwritten if it
has been provided on the ./configure command line.
