[28360cb] | 5 | <para>This package is known to behave badly when you have changed its

[2b114b25] | 6 | default optimization flags (including the -march and -mcpu options).
|
---|
| 7 | Therefore, if you have defined any environment variables that override
|
---|
| 8 | default optimizations, such as CFLAGS and CXXFLAGS, we recommend unsetting
|

[ae581da] | 9 | or modifying them when building Binutils.</para>

[b7d9d404] | 26 | <para>Normally, the <emphasis>tooldir</emphasis> (the directory where the

[ae581da] | 27 | executables end up) is set to $(exec_prefix)/$(target_alias), which expands
|
---|
| 28 | into, for example, <filename>/usr/i686-pc-linux-gnu</filename>. Since we only
|
---|
| 29 | build for our own system, we don't need this target specific directory in
|
---|
| 30 | <filename>/usr</filename>. That setup would be used if the system was used to
|
---|
| 31 | cross-compile (for example compiling a package on an Intel machine that
