Thomas Petazzoni a906c4c4fe package/netsurf: change how CFLAGS/LDFLAGS are passed 
Fixes:
http://autobuild.buildroot.net/results/eeb2863c6237aac8428e49a5ee514d43088b0fb8

In commit 6da049f8ae ("package/netsurf:
fix build"), the CC variable passed to netsurf's build system was
extended to pass some special -I and -L options needed for netsurf to
find its own headers/libraries.

Unfortunately, on some systems (including mine), it breaks the build,
due to:

  toolpath_ := $(shell /bin/which $(CC__))

when $(CC__) contains some -I/-L options, they are considered to be
options "to which", which causes the funny:

/usr/bin/make install --directory=libnslog HOST=arm-buildroot-linux-uclibcgnueabi PREFIX=/home/thomas/projets/outputs/shared-netsurf/build/netsurf-3.8/tmpusr Q=@ WARNFLAGS='-Wall -W -Wno-error' DESTDIR=
make[3]: warning: jobserver unavailable: using -j1.  Add '+' to parent make rule.
/bin/which: invalid option -- 'I'
/bin/which: invalid option -- '/'
/bin/which: invalid option -- 'h'
/bin/which: invalid option -- 'o'
/bin/which: invalid option -- 'm'
/bin/which: invalid option -- 'e'
/bin/which: invalid option -- '/'
/bin/which: invalid option -- 't'
/bin/which: invalid option -- 'h'
/bin/which: invalid option -- 'o'
/bin/which: invalid option -- 'm'
/bin/which: invalid option -- 's'
/bin/which: invalid option -- '/'
[...]
/bin/which: invalid option -- 'l'
/bin/which: invalid option -- 'b'
/bin/which: --read-alias, -i: Warning: stdin is a tty.

and the build simply hangs.

We cannot pass CFLAGS/LDFLAGS as make options, as they would override
the CFLAGS definitions in netsurf Makefiles. However, those Makefiles
use the construct:

CFLAGS := $(CFLAGS) -more-flags

so by passing CFLAGS and LDFLAGS through the make environment, which
can achieve our goal.

It is worth mentioning that it remains very fragile, because
CFLAGS/LDFLAGS are used both for building target objects but also some
host tools. The netsurf build system is really not good.

README 

Buildroot is a simple, efficient and easy-to-use tool to generate embedded
Linux systems through cross-compilation.

The documentation can be found in docs/manual. You can generate a text
document with 'make manual-text' and read output/docs/manual/manual.text.
Online documentation can be found at http://buildroot.org/docs.html

To build and use the buildroot stuff, do the following:

1) run 'make menuconfig'
2) select the target architecture and the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) find the kernel, bootloader, root filesystem, etc. in output/images

You do not need to be root to build or run buildroot.  Have fun!

Buildroot comes with a basic configuration for a number of boards. Run
'make list-defconfigs' to view the list of provided configurations.

Please feed suggestions, bug reports, insults, and bribes back to the
buildroot mailing list: buildroot@buildroot.org
You can also find us on #buildroot on Freenode IRC.
