<para>It is important that Binutils be the first package compiled

linker and assembler to determine which of their own features to

enable.</para>

<para>In order for the SBU values listed in the rest of the book

to be of any use, measure the time it takes to build this package from

the configuration, up to and including the first install. To achieve

this easily, wrap the commands in a <command>time</command>
|

command like this: <userinput>time { ../configure ... && make

&& make install; }</userinput>.</para>

<listitem>

|
<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>
