`Scripts/Makefile.rules` used MAKEFILE_LIST to obtain the current makefile path, but it did so after including some other file, so it got the included file path instead. Signed-off-by: borysp <borysp@invisiblethingslab.com>

#

# All Makefiles must follow the following conventions:
|
|
#
|
|
# - Compilation and linking steps must be done via the 'cmd' function:
|
|
# e.g., use '$(call cmd,ld_so_o)' to create a shared library using LD
|
|
#
|
|
# - File-specific build flags must be specified via variables of the format 'FLAG-filename':
|
|
# e.g., use 'LDFLAGS-libsysdb.so=...' to specify libsysdb.so-specific linker flags
|
|
#
