Description:
This directory is included to resolve gyp dependency on *.isolate when parsing
base.gyp. Although the involved target is supposed to compiled off, gyp
still tries to locate the included *.isolate. Refer below for the dependency
chain.

Dependency Chain:
base/base.gyp <= base/base_unittests.isolate <= base/base.isolate
    <= build/linux/system.isolate <= net/third_party/nss/ssl.isolate
    <= net/third_party/nss/ssl_base.isolate

File(s):
net/third_party/nss/ssl_base.isolate
