Summary 07410: verifyroms: romset may report as bad if checksums are same as parent
Description If a clone romset has the same checksums as the parent romset, and at least one used rom is available, -verifyroms will report it as bad when the user doesn't have the romset at all. It's a weird combination and verifyroms somehow gets confused.

For example, mu100r in ymmu100.cpp
Steps To Reproduce - make a fresh MAME install (either compile, or download newest version)
- put in the roms folder, this is a common LCD device.

mame -verifyroms mu100
romset "mu100" not found!

mame -verifyroms mu100b
romset "mu100b" not found!

mame -verifyroms mu100r
mu100r : xu50720.ic11 (2097152 bytes) - NOT FOUND (mu100)
mu100r : xt71420.ic11 (2097152 bytes) - NOT FOUND (mu100)

mu100r : xt462a0.ic39 (4194304 bytes) - NOT FOUND (mu100)
mu100r : xt463a0.ic38 (4194304 bytes) - NOT FOUND (mu100)
mu100r : mu100-font.bin (4096 bytes) - NOT FOUND (mulcd)
mu100r : hd44780_a00.bin (4096 bytes) - NEEDS REDUMP
romset mu100r [mu100] is bad
1 romsets found, 0 were OK.
Additional Information Bug reported by Berger (MAME Linux build)
Bug does not happen in for example fidel_excel.cpp where fexceld is the same romset as fexcel. In this case there's no rom available at all (like the LCD rom in mu100r)

I’ve addressed at least some of these kinds of issues in – please re-test this with the systems that this was reported for here.

works as expected with mu100r now
