Subject: Added a clean way for building of static PIC libraries
X-Git-Tag: v5.0~141
X-Git-Url: http://mj.ucw.cz/gitweb/?a=commitdiff_plain;h=64e1c5f18620ca22d7584f8cef7c54539adf2b27;p=libucw.git

Added a clean way for building of static PIC libraries

Defining CONFIG_STATIC_PIC adds a dependency on *-pic.a
to every pkg-config file. In addition to that, the .pc
files now contain a "picsuffix" variable which can be
overridden by the user to enable the PIC mode.
