[Buildroot] [git commit branch/2019.05.x] package/openjdk: set PATH before calling make

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=80dcda334c493678c435066e81c82a4bd68eabd9
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2019.05.x

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
