[dpdk-dev] [PATCH v2] mk: support renamed Makefile in external project

[Marko Kovacevic]

The build system made a recursive call to "make" after
creating the build directory. This recursive call used
the hard-coded filename "Makefile", which prevented
builds from working if the file was renamed and make
called using "make -f". Taking the filename from
MAKEFILES_LIST make variable fixes this.

Fixes: af75078fece3 ("first public release")
