# We enable sysroot support for gcc and binutils

# here. gen_usr_ldscript from toolchain-funcs inject full path into

# the ld script wrapper, which results in double prefix. Furthermore,

# the original motivation of this helper (bug #4411), putting dynamic

# library into /lib and static one into /usr/lib while linking to

# dynamic one first, does not apply Prefix as we don't rely on

# {/usr,}/lib separation.

# from bintuils info page: In case a sysroot prefix is configured, and

# the filename starts with the `/' character, and the script being

# processed was located inside the sysroot prefix, the filename will

# be looked for in the sysroot prefix. Otherwise, the linker will try

# to open the file in the current directory. glibc will append libdir

# and slibdir, which is prepended with $EPREFIX, to libc.so and

# libpthread.so linker scripts. That will cause double prefix if ld is

# configured with sysroot support.

# This is a dirty hack here, suggestion for alternatives welcome.
