[lttng-dev] [PATCH lttng-ust] doc: fix build failure due to wrong whitespace character

[Simon Marchi]

The previous, commit:

    54435b75df4c ("doc: reformat long lines in doc/examples/Makefile.am")

introduced the following build failure, when the support for JUL is
enabled:

    make[1]: Entering directory '/home/smarchi/build/lttng-ust/doc/examples/java-jul'
    javac -classpath "../../../liblttng-ust-java-agent/java/lttng-ust-agent-jul/lttng-ust-agent-jul.jar:../../../liblttng-ust-java-agent/java/lttng-ust-agent-common/lttng-ust-agent-common.jar:." -g Hello.java
    javac -classpath "../../../liblttng-ust-java-agent/java/lttng-ust-agent-jul/lttng-ust-agent-jul.jar:../../../liblttng-ust-java-agent/java/lttng-ust-agent-common/lttng-ust-agent-common.jar:." -g FilterChangeListenerExample.java
    javac -classpath "../../../liblttng-ust-java-agent/java/lttng-ust-agent-jul/lttng-ust-agent-jul.jar:../../../liblttng-ust-java-agent/java/lttng-ust-agent-common/lttng-ust-agent-common.jar:." -g ApplicationContextExample.java
    make[1]: *** No rule to make target ' '.  Stop.
    make[1]: Leaving directory '/home/smarchi/build/lttng-ust/doc/examples/java-jul'
    Makefile:979: recipe for target 'all-local' failed
    make: *** [all-local] Error 1

I inadvertently inserted a character that looks like a space, but that
is not a space.  make tries to interpret it as a target name, which
obviously fails.

Replace it with a proper space.
