A .pc file could contain statements of the form:
-L/usr/lib
but also:
-L/path/to/sysroot/usr/lib
The latter form typically occurs when the dependency was configured with a
statement like --with-xxx=$(STAGING_DIR)/usr.
pkgconf only expects the first form, and prefixes it with the specified
sysroot. However, this strategy would result in a double sysroot in the
second case:
-L/path/to/sysroot/path/to/sysroot/usr/lib
This patch checks for the presence of the sysroot in the specified -L or -I
directives, and only adds the sysroot when not already present.
