parisc:generic-64bit_defconfig build failures due to 'kbuild: handle libs-y archives separately...'

parisc:generic-64bit_defconfig build failures due to 'kbuild: handle libs-y archives separately...'

[Guenter Roeck]

Hi,

parisc64 builds, specifically generic-64bit_defconfig, fail to build
in mainline as follows.

hppa64-linux-ld:
hppa64-linux/bin/../lib/gcc/hppa64-linux/4.9.0/libgcc.a(_divdi3.o)(.text+0xec):
cannot reach $$divU
hppa64-linux/bin/../lib/gcc/hppa64-linux/4.9.0/libgcc.a(_divdi3.o):
In function `__divdi3':
libgcc2.c:(.text+0xec): relocation truncated to fit: R_PARISC_PCREL22F against
symbol `$$divU' defined in .text.div section in
hppa64-linux/bin/../lib/gcc/hppa64-linux/4.9.0/libgcc.a(_divU.o)
hppa64-linux-ld:
hppa64-linux/bin/../lib/gcc/hppa64-linux/4.9.0/libgcc.a(_divdi3.o)(.text+0x150):
cannot reach $$divU

[ and many more ]

This is after enabling CONFIG_MLONGCALLS; otherwise build failures are
more severe.

Building with gcc 6.3.0 fails as well with the same error.

Bisect points to commit 3a166fc2d4ef ("kbuild: handle libs-y archives
separately from built-in.o archives") as the culprit. Bisect log is
attached.

Hi all, sorry for the incomplete coverage, the team now is actively fixing build cluster problems, 
which had been down and low effectiveness. With current accumulated builds, it need
at least 1 week to recover to a good state.

We do test that config. I guess it's because the build servers are
under pressure recently. Philip/Xiaolong are looking at this issue.

Thanks for the quick fix. I'm not sure why 0day didn't catch it.
Does it build test parisc/generic-64bit_defconfig, I wonder?

Thanks,
Nick
