>Description:
Consider the following libtool command:

libtool --mode link cc -o test test.o -lfoo libbar.a

The buildlink3 infrastructure processes and reorders this to:
${WRKSRC}/.gcc/bin/gcc -o test test.o libbar.a -L${WRKSRC}.buildlink/lib \
-I${WRKSRC}.buildlink/include -lfoo

Note that the order of the libraries has changed. This can cause
unresolved externals.

Notably net/arla suffers from this as the Makefiles of this package
use both alternatives, "../../lib/foo/libfoo.a" and "-L../../lib/foo -lfoo"
to specify libraries.

>How-To-Repeat:
Try to build net/arla without the numerous patches to work around this.

>Fix:
Not provided.
