This reverts commit 43365ca662 ("Do not use $(V) - force AM_V=1") as
it breaks verbose output in automake packages, deviating from the
upstream and expected behaviour.
As you can see, neither make command outputs the expected verbose
compile command lines:
```
$ make package/mtd-utils/{clean,compile} V=sc
...
CCLD lsmtd
CC nand-utils/nanddump.o
CCLD nanddump
...
```
```
$ make -C build_dir/target*/mtd-utils-2.1.1 clean
...
$ make -C build_dir/target*/mtd-utils-2.1.1 V=1
...
CC lib/libmtd.o
CC lib/libfec.o
CC lib/common.o
CC lib/libcrc32.o
```
The original reason for this commit was some packages failing to build
if V is set to something other than 0 or 1. See the discussion in PR
https://github.com/openwrt/openwrt/pull/2481 for how to fix this in the
package Makefile.

Build broke as distributions now include Perl 5.26 and automake
triggered an "Unescaped left brace in regex" error.
Import upstream commit 13f00eb449 to fix that.

The rework of the host tools discovery caused automake to embed
absolute paths to staging_dir/host/bin/perl into the shebang
of the generated automake executables.
Switch to the portable "/usr/bin/env perl" and enable global
warnings through "$^W" instead of the "-w" interpreter argument.

Projects using silent-rules might otherwise fail to compile.
This is due to the following resulting Makefile code:
AM_V_P = $(am__v_P_$(V))
am__v_P_ = $(am__v_P_$(AM_DEFAULT_VERBOSITY))
am__v_P_0 = false
am__v_P_1 = :
Automake directly uses $(V) for variable name expansion
which fails if $(V) is set to sth. else other than '0' or '1'.
This patch forces automake to not take $(V) into account
but to always use the default config for verbosity.
A better approach would be to actually take $(V) into account,
however not just pass it through (AM_V='$(V)') but
set AM_V to 0 if $V=0 / unset and to 1 otherwise.
This plan however is foiled due to my frustration about
automake as well as my lack of m4 skills.
