[Buildroot] [PATCH v2, 1/1] package/openjdk: set PATH before calling make

[Fabrice Fontaine]

PATH must be set to $(BR_PATH) thanks to $(TARGET_MAKE_ENV) before
calling make otherwise build fails on:
/bin/bash: gawk: command not found

When build fails, config.log contains the following line:

configure:13709: checking for gawk
configure:13725: found /home/buildroot/autobuild/run/instance-3/output/host/bin/gawk
configure:13736: result: gawk
[...]
ac_cv_prog_AWK=gawk

Changes v1 -> v2 (after review of Arnout Vandecappelle):
 - Set PATH thanks to $(TARGET_MAKE_ENV) instead of setting AWK
