linux-bug: fix undefined reference to `__gnu_mcount_nc' issue and bump PR
Without that fix we have:
LD .tmp_vmlinux1
init/built-in.o: In function `run_init_process':
calibrate.c:(.text+0x10): undefined reference to `__gnu_mcount_nc'
init/built-in.o: In function `init_post':
calibrate.c:(.text+0x3c): undefined reference to `__gnu_mcount_nc'
init/built-in.o: In function `do_one_initcall':
calibrate.c:(.text+0x148): undefined reference to `__gnu_mcount_nc'
init/built-in.o: In function `name_to_dev_t':
calibrate.c:(.text+0x2cc): undefined reference to `__gnu_mcount_nc'
init/built-in.o: In function `set_reset_devices':
calibrate.c:(.init.text+0x10): undefined reference to `__gnu_mcount_nc'
init/built-in.o:calibrate.c:(.init.text+0x38): more undefined references to `__gnu_mcount_nc' follow
make: *** [.tmp_vmlinux1] Error 1
FATAL: oe_runmake failed
Thanks khem in #oe on Freenode on irc for help:
Feb 14 19:21:26 <khem> GNUtoo|laptop: are you using profiling
[...]
Feb 14 19:57:13 <khem> GNUtoo|laptop: ok so here it your problem you are passing -pg
Feb 14 19:57:16 <khem> to compiler
[...]
Feb 14 19:58:11 <khem> GNUtoo|laptop: thats only useful if you will provide mcount and other profiling hook implementation
Feb 14 19:58:16 <khem> compiler sort of expects it
The solution I chose was to disable the CONFIG_FTRACE that added -pg (profiling compiler option)
