Indeed, I don't really know what I'm talking about.
On my system I have installed

$ apt show fontconfig
Package: fontconfig
Version: 2.13.0-5

which includes a libfontconfig1 package of that same version.

In my system directories I have:

$ ls -l /usr/lib/x86_64-linux-gnu/ | grep fontconfig
-rw-r--r--  1 root root   492422 Mai 14 10:32 libfontconfig.a
lrwxrwxrwx  1 root root       23 Mai 14 10:32 libfontconfig.so -> 
libfontconfig.so.1.11.1
lrwxrwxrwx  1 root root       23 Mai 14 10:32 libfontconfig.so.1 -> 
libfontconfig.so.1.11.1
-rw-r--r--  1 root root   273368 Mai 14 10:32 libfontconfig.so.1.11.1

and within the LilyPond installation (like you)

$ ls -l ~/software/lilypond/releases/2.19.82/usr/lib/ | grep fontconfig
-rwxr-xr-x  1 uliska uliska    1086 Jun 24 14:10 libfontconfig.la
lrwxrwxrwx  1 uliska uliska      22 Mai 20  2017 libfontconfig.so -> 
libfontconfig.so.1.9.2
lrwxrwxrwx  1 uliska uliska      22 Mai 20  2017 libfontconfig.so.1 -> 
libfontconfig.so.1.9.2
-rwxr-xr-x  1 uliska uliska  270584 Jun 24 14:12 libfontconfig.so.1.9.2

Am I right to think that LilyPond uses the bundled library (1.9.2?) 
while fc-list uses 1.11.1?
If so, would that be an explanation for the differences in the reported 
font names? Or could it be related to some code in LilyPond, how that 
*uses* fontconfig?
