Crashpad is not supposed to work on Linux yet. There is no reason to have a bug 
for that at this point.

mini_chromium is supposed to work on Linux, and your build log shows a problem 
compiling mini_chromium for Linux. 

I fixed the problem from your build log in 
https://chromium.googlesource.com/chromium/mini_chromium/+/8c599712d10ca3be55251
ff28f400edfcff5dcfd. I also fixed other Linux build problems in 
https://chromium.googlesource.com/chromium/mini_chromium/+/e38cddb8357190387a06a
680787979781b3d5f04 and
