Really did not get the first question. Regarding PERL being set
twice, I am just trying to manipulate it to the actual host binary,
is there a better way? 'which perl' or 'env perl' will only point to
the symlink under HOSTTOOLS.
1. You are replacing
#!/usr/bin/env perl
with
#! <result of calling `readlink -f ${PERL}`>
The first line will guarantee a short shebang, while the second one may
result in a very long shebang which may hit the hardcoded kernel limit.
So you are effectively adding the problem instead of fixing it (and
there is nothing to be fixed).
2. You do this:
PERL=`which perl`
PERL=`readlink -f ${PERL}`
There is no need for the first line, if PERL is immediately set to
something else.
