[81fd230] | 32 | <para>It is important that Binutils be the first package compiled
|
---|
| 33 | because both Glibc and GCC perform various tests on the available
|
---|
| 34 | linker and assembler to determine which of their own features to
|
---|
| 35 | enable.</para>
|
---|
| 36 |
|
---|
| 37 | <para>This package is known to have issues when its default
|
---|
| 38 | optimization flags (including the <parameter>-march</parameter> and
|
---|
| 39 | <parameter>-mcpu</parameter> options) are changed. If any environment
|
---|
| 40 | variables that override default optimizations have been defined, such
|
---|
| 41 | as <envar>CFLAGS</envar> and <envar>CXXFLAGS</envar>,
|
---|
| 42 | unset them when building Binutils.</para>

| 44 | <para>The Binutils documentation recommends building Binutils outside of the
