I think this is not the problem. The attached patch does exactly that.
The problem is that the fonts are "appended" to the configuration,
such that other fonts may be found and used instead of ours.
Look at the following example.
I removed the latex-xft-fonts package, launched "lyx -dbg font", and
got what you can see in the dbg_fonts1.txt attachment.
As you can see, cmsy10, cmmi10, cmr10, and cmex10 were still found,
even without latex-xft-fonts, as they are now coming from
/usr/local/share/fonts/mathml/{cmex10,cmmi10,cmr10,cmsy10}.ttf
Then I applied the patch and launched again "lyx -dbg font", getting
the result you can see in the dbg_fonts2.txt attachment.
Curiously, the wasy10 font is not found, even if it is found when
its directory is listed in the fontconfig configuration files.
However, the point here is that the cmsy10, cmmi10, cmr10, and cmex10
fonts are still those in /usr/local/share/fonts/mathml, and even if
their glyphs are correct, they do not match the other bakoma fonts.
This can be seen by looking at the \Omega glyph as compared to the
\mho glyph.
I don't know how to persuade fontconfig into taking our fonts instead
of other matching ones. Using the configuration files instead of the
API functions, this is accomplished by listing first the right
directories.
