[PATCH 2/2] Makefile: consider LDFLAGS on feature tests and when linking executables

While we have an LDFLAGS variable in kvmtool's Makefile, it's not really used when both doing the feature tests and when finally linking the lkvm executable. Add that variable to all the linking steps to allow the user to specify custom library directories or linker options on the command line.

[PATCH 1/2] Makefile: allow overriding CFLAGS on the command line

When a Makefile variable is set on the make command line, all Makefile-internal assignments to that very variable are _ignored_. Since we add quite some essential values to CFLAGS internally, specifying some CFLAGS on the command line will usually break the build (and not fix any include file

[PATCH 0/2] kvmtool: allow CFLAGS and LDFLAGS override

In the past there have been some complaints from cross-compilation users about missing libraries and include files. Fixing those issues by pointing make to the proper directories via CFLAGS and LDFLAGS proved to be complicated. This series fixes this, so custom CFLAGS and LDFLAGS can be given on
