[Buildroot] [PATCH 1/1] package/s390-tools: fix build error due to undefined KMS_PLUGIN_LOCATION

[Alexander Egorenkov <egorenar@linux.ibm.com>]

Fixes the following build error:
kms.c:44:2: error: #error KMS_PLUGIN_LOCATION must be defined
   44 | #error KMS_PLUGIN_LOCATION must be defined
      |  ^~~~~
/usr/bin/make -C ../..//libutil/ libutil.a
kms.c: In function ?load_kms_plugin?:
kms.c:274:5: error: ?KMS_PLUGIN_LOCATION? undeclared (first use in this function)
  274 |     KMS_PLUGIN_LOCATION, so_name);
      |     ^~~~~~~~~~~~~~~~~~~
kms.c:274:5: note: each undeclared identifier is reported only once for each
function it appears in

+Subject: [PATCH 1/1] zkey: Fix build error when the compiler flags are
+ overridden
+
+When the compiler flags are overridden, the build of zkey may fail with:
+
+kms.c:44:2: error: #error KMS_PLUGIN_LOCATION must be defined
+   44 | #error KMS_PLUGIN_LOCATION must be defined
+      |  ^~~~~
+
+The Makefile uses CFLAGS variable for defining the KMS_PLUGIN_LOCATION,
+but it should rather use ALL_CFLAGS.
+
+Also use ALL_CPPFLAGS for defining HAVE_LUKS2_SUPPORT.
+
+Fixes: https://github.com/ibm-s390-linux/s390-tools/issues/108
