arm64: standards: Fix LSB info

The standard page wasn't adapted for ARM64 since day one. Remove
the references to IA32 and AMD64, and state there's no ARM64
specific part of LSB. Also we cannot satisify some (really
unreasonable) requirements on symbol versions with Glibc on ARM64.

(cherry picked from commit adb257913e426c83c423d9f102c7a51a9cd63004)

Edited for ARM64.

17 possible. The primary standards are:</para>

34 <para>The LSB has four separate specifications: Core, Desktop,
35 Languages, and Imaging. Some parts of Core and Desktop
36 specifications are architecture specific. There are also two trial
37 specifications: Gtk3 and Graphics. There's no architecture specific
38 parts for ARM64, and on ARM64 Glibc has intentionally left out
39 some symbol versions required by the architecture independant part of
40 LSB Core. So we cannot satisfy the LSB architecture independant
41 parts, but we still use them as a reference.</para>
42
43 <note><para>Many people do not agree with these requirements.
44 The main purpose of the LSB is to ensure that proprietary software
45 can be installed and run on a compliant system.
46 Since LFS is source based, the user has complete control over what
47 packages are desired; you may choose not to install some packages that
48 are specified by the LSB.</para></note>

54 certification tests <quote>from scratch,</quote> this can't be done without many additional packages

56 additional packages can be found in BLFS. </para>
