makedumpfile: import 1.7.5 from meta-openembedded

The kdump script from kexec-tools does not work without makedumpfile (see https://git.yoctoproject.org/poky/tree/meta/recipes-kernel/kexec/kexec-tools/kdump#n14 ).
Thus, let's import makedumpfile from meta-openembedded/meta-oe/recipes-kernel/makedumpfile and make kexec-tools RDEPENDS on makedumpfile.

makedumpfile is the utility which reads /proc/vmcore after a kernel panic and creates a kdump file under /var/crash/.

+Subject: [PATCH] makedumpfile: replace hardcode CFLAGS
+
+* Create alias for target such as powerpc as powerpc32
+* Remove hardcode CFLAGS
+* Add CFLAGS_COMMON to instead of CFLAGS so can flexibly
+  customize CFLAGS and not hardcode the CFLAGS as previously
+* Forcibly to link dynamic library as the poky build
+  system doesn't build static library by default
+
+Upstream-Status: Inappropriate [oe specific]
