In miktex fontconfig (which is a miktex specific fontconfig)
searches fonts/type1, fonts/truetype and fonts/opentype in all
texmf-trees.

You could test with \XeTeXtracingfonts=1 with various fonts. The
log-file should tell you where the xetex of texlive gets the font
file from.

This means that the .ignore thing is miktex specific (and as I just
tested: it helps with luatex/mkluatexfontdb). Moving the font to
fonts/truetype.ignore seems to work for both engines.
