Ideally not, but some upstream packages have such hardcodings and such.
It can be our compiler wrapper transforms some of those automatically, or
removes them.
We run the compiler with -h or so at the beginning of each package build in
wrapper debug mode to log the compiler wrapper transforms applied (append,
insert, remove, …)
Getting arbitrary upstream packages to cross compile requires exactly such kind
of things to fix, workaround polish, or other such things to set up.
