Summary	07252: LISTXML: sourcefile="" for devices sometimes show fullpath information in -lx
Description	For the same devices each time, the "sourcefile=" source path contains fullpath information rather than relative paths starting at "src". I noticed this starting to happen when I began to compile daily builds on a RAMDISK (R:) - specifically r:\mame contains the source, with the devices in question showing "r:/mame/src/......" as "sourcefile=" rather than "src/......"
Steps To Reproduce
Additional Information	I noticed looking at the source which controls this @ "src\frontend\mame\info.cpp" that effort is made to parse this literal path information from the normal non-device machine sourcefiles - but no effort is made when the device machine line is created. The problems that show up for me involve only 2 locations (making up 58 devices as of this writing): - <machine name="dac" sourcefile="r:/mame/src/devices/sound/dac.h" isdevice="yes" runnable="no"> - <machine name="i80c51" sourcefile="r:/mame/src/devices/cpu/mcs51/mcs51.cpp" isdevice="yes" runnable="no"> The remaining devices (4278 as of this writing) are showing the relative path as expected.
