| 30 | <para>It is important that Binutils be the first package to get compiled,

| 31 | because both Glibc and GCC perform various tests on the available linker and

| 32 | assembler to determine which of their own features to enable.</para>

[6e41459] | 34 | <para>This package is known to have issues when its default

[574b0ea] | 35 | optimization flags (including the <parameter>-march</parameter> and

[24a08b9] | 36 | <parameter>-mcpu</parameter> options) are changed. If any environment
|

| 37 | variables that override default optimizations have been defined, such
