Loïc Yhuel 467b08a782 [ELF] Fix absolute paths handling in linker scripts
With toolchains using a relative sysroot, like crosstool-ng, gcc/clang will call the linker
with something like "--sysroot=/path/bin/../machine/sysroot".
The is_in_sysroot detection wasn't working in this case.

Since to_abs_path() uses lexically_normal() for relative paths, it seems consistent to do
the same for absolute paths instead of modifying is_in_sysroot().
