How do I avioid a plugin to be loaded in lto1

[Andres Tiraboschi <andres.tiraboschi@xxxxxxxxxxxxxxxxxxxxxx>]

I'm making a plugin and I'm trying to compile a file in this way:

gcc -o myprog -fplugin=./myPlugin.so -flto andres.c

and I'm having the following issue:

lto1: error: cannot load plugin: .../myPlugin.so
.../myPlugin.so: undefined symbol: parse_in
lto-wrapper: /home/andres/Escritorio/gcc-4.9.2/install/bin/gcc
returned 1 exit status
/usr/bin/ld: lto-wrapper failed
collect2: error: ld returned 1 exit status


I'd like to know if there's some way to avoid lto1 trying to load my plugin.

Regards,
Andrés.
