Subject: [PATCH] gcc-plugins: Enable error message print
From: He Zhe <zhe.he@...driver.com>
Instead of sliently emptying CONFIG_PLUGIN_HOSTCC which is the dependency
of a series of configurations, the following error message would be easier
for users to find something is wrong and what is happening.
scripts/gcc-plugins/gcc-common.h:5:22: fatal error: bversion.h:
No such file or directory
compilation terminated.
Now that we have already got the error message switch, let's turn it on.
