etc/ directory missing in unixodbc 2.3.5

[v-makouz]

I noticed that after installing unixodbc 2.3.5 the folder /usr/local/Cellar/unixodbc/2.3.5/etc/ is missing

When I manually extracted the following two packages:
https://homebrew.bintray.com/bottles/unixodbc-2.3.4.el_capitan.bottle.tar.gz
https://homebrew.bintray.com/bottles/unixodbc-2.3.5.el_capitan.bottle.tar.gz

I saw that indeed the 2.3.5 version didn't have the etc/ in it (but does have .brew/ which 2.3.4 doesn't have). I was also trying it on High Sierra VM and encountered the same issue, so it isn't just El Capitan

Should be fixed by #22939 which will also relocate it to /usr/local/etc

@v-makouz also note this is actually a Makefile bug. Makefile.am has

install-data-am:
        -touch $(DESTDIR)${sysconfdir}/odbcinst.ini
        -touch $(DESTDIR)${sysconfdir}/odbc.ini
        -mkdir -p $(DESTDIR)${sysconfdir}/ODBCDataSources
        cp unixodbc_conf.h $(DESTDIR)${includedir}/unixodbc_conf.h

which fails if $(DESTDIR)${sysconfdir} doesn't already exist.

This is now fixed if you brew update and brew upgrade
