app-i18n/opencc sometimes fails to build with parallelization (-jX where X >= 2). It seems that multiple custom targets try to copy locally built libopencc.so.1.0.0 into the same directory, and it can fail with error 'Error copying file ".../src/libopencc.so.1.0.0" to ".../src/tools".'.

According to the upstream commit, it seems we don't need the copy command on Linux. I also confirmed that build pass without the copy command. https://github.com/BYVoid/OpenCC/commit/572ec0a6828331f6ab86c742a783fd57440eeabe I'll add patch to drop the command.
The bug has been closed via the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=50be00f6ee1ce7eaa585389586a5d838e65e647b commit 50be00f6ee1ce7eaa585389586a5d838e65e647b Author: Naohiro Aota <naota@gentoo.org> AuthorDate: 2018-10-09 17:56:23 +0000 Commit: Naohiro Aota <naota@gentoo.org> CommitDate: 2018-10-09 17:57:31 +0000 app-i18n/opencc: add patch to avoid conflicting copy copy command is only necessary in VS build, and it's causing conflict on parallel build. Dropping the command is safe on Linux.
