Hi, Dear Maintainers

I met an issue when try to compile automake with the perl installed in a very long path which larger then max length of shebang , here is the reproduce steps

git clone git@github.com:autotools-mirror/automake.git; cd automake
./bootstrap
./configure
make

Failed with error:

...

GEN doc/aclocal-1.17.1

help2man: can't get `--help' info from bin/aclocal

Try `--no-discard-stderr' if option outputs to stderr

make: *** [Makefile:3818: doc/aclocal-1.17.1] Error 2

The failure is caused by the long path of the perl in aclocal.in, the shebang is cutted. Could we change it like following diff?

diff --git a/bin/aclocal.in b/bin/aclocal.in

index 4d01f3a4d..73d5ee47f 100644
