Do not litter the source directory with build artifacts
Do not litter the source directory with build artifacts

Before, building locally left a file named "vboot_host.pc" in the
top directory.

With this change, it's put into the $BUILD directory where it
belongs.

It still gets installed into the same place, of course.

BUG=chromium:459338
BRANCH=none
TEST=make runtests, and

Run:

  make test_setup MINIMAL=
  make test_setup MINIMAL=1
  find . -name vboot_host.pc

Before this CL:

  ./build/install_for_test/usr/lib/pkgconfig/vboot_host.pc
  ./build/install_for_test/lib/pkgconfig/vboot_host.pc
  ./vboot_host.pc

After this CL:

  ./build/install_for_test/usr/lib/pkgconfig/vboot_host.pc
  ./build/install_for_test/lib/pkgconfig/vboot_host.pc
  ./build/vboot_host.pc
