relax host system requirements 
A requirement on Glibc is not needed at all.  It's enough once
$LFS_TGT-* is runnable.  A test on Alpine (using musl as libc) has
practically proved this.

We'd raised binutils and GCC requirements mostly for Glibc.  But now
Glibc is cross compiled by our cross toolchain with latest GCC and
binutils release, the host tools really does not matter.  In the Glibc
building process only two .c files are build with BUILD_CC (the C
compiler from the host), and they are highly conservative (mostly
unchanged for years).

Binutils does not have too much requirement on host GCC & Binutils:
there is even a Binutils commit in this week fixing a build failure with
GCC-4.2!

So the most strict limitation comes from GCC.  GCC requires host GCC to
support ISO C++ 11 so GCC >= 4.8 is needed.  And both GCC-4.8 and latest
GCC-11.2 claims a requirement for Binutils-2.12 (for x86_64) or 2.13.1
(for 32-bit x86), so we make minimal Binutils version 2.13.1.

And, host bzip2 is never used now: the only .tar.bz2 files are elfutils
and python docs.  They are not decompressed before entering chroot.

gcc-pass1: set --with-glibc-version to target glibc version 
"info gccinstall" says:

'--with-glibc-version=MAJOR.MINOR'
     Tell GCC that when the GNU C Library (glibc) is used on the target
     it will be version MAJOR.MINOR or later.  Normally this can be
     detected from the C library's header files, but this option may be
     needed when bootstrapping a cross toolchain without the header
     files available for building the initial bootstrap compiler.

So it can, and should be set to the version of glibc which will be built
for the chroot environment.

On x86_64, currently it does not make any difference with values >=
2.13.  But it may make a difference if a new feature is added to glibc,
or on other platforms.
