Subject: [PATCH] gcc: Fix argument list too long error.

There would be an "Argument list too long" error when the
build directory is longer than 200, this is caused by:

headers=`echo $(PLUGIN_HEADERS) | tr ' ' '\012' | sort -u`

The PLUGIN_HEADERS is too long before sort, so the "echo" can't handle
it, use the $(sort list) of GNU make which can handle the too long list
would fix the problem, the header would be short enough after sorted.
The "tr ' ' '\012'" was used for translating the space to "\n", the
$(sort list) doesn't need this.

RP: gcc then added *.h and *.def additions to this list, breaking the original
fix. Add the sort to the original gcc code, leaving the tr+sort to fix the original
issue but include the new files too as reported by Zhuang <qiuguang.zqg@alibaba-inc.com>

Upstream-Status: Backport [https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=66e157188bd2f789809e17e85f917534c9381599]
