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

because both Glibc and GCC perform various tests on the available

linker and assembler to determine which of their own features to

enable.</para>

<para>The Binutils documentation recommends building Binutils

in a dedicated build directory:</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
