[Makefile]File + constant problem

Hi guys,
I am writing a Makefile with some strange features.
What I have is:
list of files *.efi
list of guids (guid is just a number)

one *.efi file is supposed to be used with one guid, so efi file and guid is a pair.

What I need is:
list of files *.fv

How to make *.fv file from *.efi file?

Code:

 
$(SOME_COMMAND)  efi_file -some_flags   # produces *.efi.xyz file
$(ANOTHER_COMMAND) efi_xyz_file -some_flags guid # produces *.fv file

So $(SOME_COMMAND) and ($ANOTHER_COMMAND) must be done for each of *.efi - guid pair.

E.g

Code:

 
files = first.efi second.efi
guid = 544 123
 
#what must be done is:
$(SOME_COMMAND)  first.efi -some_flags   # produces first.efi.xyz file
$(ANOTHER_COMMAND) first.efi.xyz -some_flags 544 # prudces first.fv
 
$(SOME_COMMAND)  second.efi -some_flags   # produces second.efi.xyz file
$(ANOTHER_COMMAND) second.efi.xyz -some_flags 123 # produces second.fv

Do you have any concept how to prepare such a makefile? I tried with for loop but it's not designed to be used inside makefiles...

NAME

       systemd-efi-boot-generator - Generator for automatically mounting the EFI System Partition used by the current boot to /boot

SYNOPSIS

       /usr/lib/systemd/system-generators/systemd-efi-boot-generator

DESCRIPTION

       systemd-efi-boot-generator is a generator that automatically creates mount and automount units for the EFI System Partition (ESP), mounting
       it to /boot. Note that this generator will execute no operation on non-EFI systems, on systems where the boot loader does not communicate
       the used ESP to the OS, on systems where /boot is an explicitly configured mount (for example, listed in fstab(5)) or where the /boot mount
       point is non-empty. Since this generator creates an automount unit, the mount will only be activated on-demand, when accessed.

       systemd-efi-boot-generator implements the generator specification[1].
