I'm not quite sure I understand the expected behaviour. For now the
behaviour is the following:
- when specifying an absolute path to a _real_ lib, the sysroot prefix
is prepended.
- when specifying a relative path to a _real_ lib, the sysroot prefix
is _NOT_ prepended.
- when specifying an absolute path to a linker script, containing a
link with an absolute path, the sysroot prefix is _NOT_ prepended.
- when specifying an absolute path to a linker script, containing a
link with a relative path, the sysroot prefix is _NOT_ prepended.
- when specifying an relative path to a linker script, containing a
link with an absolute path, the sysroot prefix is _NOT_ prepended.
- when specifying an relative path to a linker script, containing a
link with an relative path, the sysroot prefix is _NOT_ prepended.

with my patch, the behaviour is as follows:
- when specifying an absolute path to a _real_ lib, the sysroot prefix
is prepended.
- when specifying a relative path to a _real_ lib, the sysroot prefix
is _NOT_ prepended.
- when specifying an absolute path to a linker script, containing a
link with an absolute path, the sysroot prefix is prepended.
- when specifying an absolute path to a linker script, containing a
link with a relative path, the sysroot prefix is _NOT_ prepended.
- when specifying an relative path to a linker script, containing a
link with an absolute path, the sysroot prefix is prepended.
- when specifying an relative path to a linker script, containing a
link with an relative path, the sysroot prefix is _NOT_ prepended.

Is this the behaviour you would expect?
