Subject: Allow statically linking compiler support libraries when linking a library
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=2f505131b5f29b0de6338bf9d13b7ceadf617d96;p=thirdparty%2Flibtool.git

Allow statically linking compiler support libraries when linking a library

For cases with deplibs_check_method="file_magic ..." (as it is for mingw),
there were previously no way that a static library could be accepted
here.
