It looks like this file is not build on iOS when using gyp. I guess we should
also add in base/base.gypi then.

this looks like it is pulled in to me:

https://code.google.com/p/chromium/codesearch?q=base.gypi#chromium/src/base/b...

[sdefresne, 2015/08/04 07:42:01]

It isn't, because the regexp does not match the file path:

$ find base -name sys_string_conversions_mac_unittest.mm
base/strings/sys_string_conversions_mac_unittest.mm

The regexp should be "^strings/sys_string_conversions_mac_unittest\\.mm$". Maybe
we need to change the gyp file too then.
