<para>By default, the linker would generate both the GNU-style
hash table and the classic ELF hash table for shared libraries and
dynamically linked executables. The hash tables are only intended
for a dynamic linker to perform symbol lookup. On LFS the dynamic
linker (provided by the Glibc package) will always use the
GNU-style hash table which is faster to query. So the classic
ELF hash table is completely useless. This makes the linker
only generate the GNU-style hash table by default, so we can avoid
wasting time to generate the classic ELF hash table when we build
the packages, or wasting disk space to store it.</para>
<para>By default, the linker would generate the classic ELF hash
table for shared libraries and dynamically linked executables
because the GNU-style hash table is incompatible with the MIPS o32
ABI. The hash tables are only intended for a dynamic linker to
perform symbol lookup. On LFS the dynamic linker (provided by the
Glibc package) supports the GNU-style hash table, and this LFS
edition does not support the o32 ABI. So this is used to make the
linker generate the GNU-style hash table instead of the classic
ELF hash table by default, as the GNU-style hash table is faster
to query.</para>
