【49】新版pciutils解決undefined reference to `udev_hwdb_get_properties_list_entry

只需要在調用pcituils lib的makefile增加-ludev

還有一種改法就是直接修改pciutils的Makefile，簡單粗暴，不detect系統配置，直接寫成no，反正這兩個lib沒啥太大用處

Use libkmod to resolve kernel modules on Linux (yes/no, default: detect)

LIBKMOD=no

Use libudev to resolve device names using hwdb on Linux (yes/no, default: detect)

HWDB=no
