[openib-general] [patch] tvflash configure checks for libpci

[Bernhard Fischer]

Hi,

tvflash does check if pci/pci.h is installed but does not error out if
it is not found.
This leads to build-errors later on as the include is not found.

Attached patch would
- check for pci/pci.h and bail out if it is not found.
- check for needed functions provided by libpci

Please consider applying something to this effect.
Thank you
