<glossdef>
<para>
Specifies architecture-specific linker flags for
the target system.
The set of flags is based on the selected tune features.
<filename>TUNE_LDARGS</filename> is set using
the tune include files, which are typically under
<filename>meta/conf/machine/include/</filename> and are
influenced through <filename>TUNE_FEATURES</filename>.
For example, the
<filename>meta/conf/machine/include/x86/arch-x86.inc</filename>
file defines the flags for the x86 architecture as follows:
<literallayout class='monospaced'>
TUNE_LDARGS += "${@bb.utils.contains("TUNE_FEATURES", "mx32", "-m elf32_x86_64", "", d)}"
</literallayout>
<note>
Board Support Packages (BSPs) can supply their own
set of flags.
