PATCH 1/1 package/erlang: add optional dependency to unixodbc

Quote from erlang configure without unixodbc:

checking for odbc in standard locations... no
configure: WARNING: No odbc library found skipping odbc
configure: WARNING: "ODBC library - header check failed"
configure: WARNING: "ODBC library - link check failed"

Quote from erlang configure with unixodbc:

checking for odbc in standard locations... -L/home/buildroot/br3_couchdb/output/host/usr/i586-buildroot-linux-uclibc/sysroot/usr/lib checking for SQLAllocHandle in -lodbc... yes

To check for unixodbc support used by erlang use readelf:

$ output/host/usr/bin/i586-buildroot-linux-uclibc-readelf -a output/target/usr/lib/erlang/lib/odbc-2.11.1/priv/bin/odbcserver | grep NEEDED

 0x00000001 (NEEDED)                     Shared library: [libc.so.0]

Tested using this minimal defconfig:

BR2_PACKAGE_ERLANG=y
BR2_PACKAGE_ERLANG_SMP=y
BR2_PACKAGE_UNIXODBC=y

Looks good to me. I tried it out by running Erlang, starting the odbc application and running a couple functions against it to see that it would call into the library fine. I didn't connect to a database, but I could tell that it was interacting with the unixodbc library based on the error messages. If something changes and you need to test it again, I think this is sufficient:

# erl
Eshell V7.3  (abort with ^G)
1> odbc:start().
ok
2> odbc:connect("DSN=sql-server;UID=aladdin;PWD=sesame", []).
{error,"[unixODBC][Driver Manager]Data source name not found, and no
default driver specified SQLSTATE IS: IM002 Connection to database
failed."}
