Usage: cross-fix-root <sysroot> <cross-bindir> <cross-prefix>
cross-fix-root <cross-prefix>
cross-fix-root # takes settings from env
Environment variables:
CROSS_COMPILE=<cross-prefix>
(SYSROOT|ROOT|STAGEDIR)=<sysroot>
Description:
Fix library perms and mung paths in libtool linker scripts & random -config
scripts to point to our SYSROOT directory. Add symlinks for the -config
with cross-compiler prefixes as autotool packages will search for them first
when cross-compiling.
