Chromium built as an executable shared library?

[MidwestGeek]

I built Chromium from the source code on linux. And, I ran "file
chrome", and I got

chrome: ELF 64-bit LSB shared object, AMD x86-64, version 1 (SYSV),
for GNU/Linux 2.6.9, not stripped

So, this chrome executable is actually a shared library? Does anybody
know why the binary executable is built as a shared object? Is there
any option that I can use to control the building process, so that I
will get a "pure" executable, instead of such executable shared
library?

Thanks!

How do you build your chrome?
It seems the default build is static build, a shared library build
need to update gyp file like: ./build/gyp_chromium -D
component=shared_library -D disable_nacl=1

Thanks & Best regards
