MINOR: build: add linux-glibc-legacy build TARGET
As discussed in issue #128, introduce a new build TARGET
linux-glibc-legacy to allow the build on old, legacy OS.
Should be backported to 2.0.

To build haproxy, you have to choose your target OS amongst the following ones
and assign it to the TARGET variable :
- - linux-glibc for Linux kernel 2.6.28 and above
- - solaris for Solaris 8 or 10 (others untested)
- - freebsd for FreeBSD 5 to 12 (others untested)
- - netbsd for NetBSD
- - osx for Mac OS/X
- - openbsd for OpenBSD 5.7 and above
- - aix51 for AIX 5.1
- - aix52 for AIX 5.2
- - cygwin for Cygwin
- - haiku for Haiku
- - generic for any other OS or version.
- - custom to manually adjust every setting

You may also choose your CPU to benefit from some optimizations. This is
particularly important on UltraSparc machines. For this, you can assign
