kbuild: rename ld-option to cc-ldoption
ld-option is misnamed as it test options to gcc, not to ld. Renamed it to reflect this. Cc: Andi Kleen <andi@firstfloor.org> Cc: Roland McGrath <roland@redhat.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

The second argument is optional, and if supplied will be used
|
||||
if first argument is not supported.
|
||||
|
||||
ld-option
|
||||
ld-option is used to check if $(CC) when used to link object files
|
||||
cc-ldoption
|
||||
cc-ldoption is used to check if $(CC) when used to link object files
|
||||
supports the given option. An optional second option may be
|
||||
specified if first option are not supported.
|
||||
|
||||
Example:
|
||||
#arch/i386/kernel/Makefile
|
||||
vsyscall-flags += $(call ld-option, -Wl$(comma)--hash-style=sysv)
|
||||
vsyscall-flags += $(call cc-ldoption, -Wl$(comma)--hash-style=sysv)
|
||||
|
||||
In the above example, vsyscall-flags will be assigned the option
|
||||
-Wl$(comma)--hash-style=sysv if it is supported by $(CC).
