Add CFLAGS and LDFLAGS for each feature to be checked. This allows
to pass flags and parameters to the feature checks compilation.
Use the per-feature check flags for the unwinding feature in order
to correctly compile the libunwind and libunwind-debug-frame feature
checks.
This change set simplifies the flags passing mechanism between the
Makefiles in config/Makefile and config/feature-checks; this
could be farther optimized by moving the compilation flags to the
per-feature check flags for all features to be checked.
Tested on ARMv7 and ARMv8 with 'make DEBUG=1 LIBUNWIND_DIR=/usr/local
-C tools/perf'
Jean Pihet (2):
perf: add per-feature check flags
perf: unwinding: use the per-feature check flags

Jonghwan Choi reported an issue with this patch. He asked me
to look at: 6e45eb
And so following diff is updated for this patch in my repo.. Will get
that fixed in V4:

Hi,
I am trying to update latest upstream kernel on mphackbox TC2 board
according to this wiki.
https://wiki.linaro.org/Platform/LAVA/DevOps/TC2TilesOnLavaServer/hackbox
I use vexpress-v2p-ca15_a7.dts and vexpress_defconfig kernel config.
after make kernel and dtb images, I updated them as u-zimage.bin and
u-dtb.bin. but the kernel keep panic:
Did I miss sth or the just kernel broken?
