[Buildroot] scons and check

Hi

I'm trying to create a package for Galera, a library needed by mariadb
galera cluster. It builds with scons. Galera depends on check so I
created a package for this library too, which seems to build and
install correctly.

A few packages in buildroot already use scons (exfat, exfat-utils,
benejson, gpsd). Their build commands look like this:

FOO_SCONS_ENV = $(TARGET_CONFIGURE_OPTS)
FOO_SCONS_OPTS = "prefix=/usr"

define FOO_BUILD_CMDS
        cd $(@D) && \
	 $(FOO_SCONS_ENV) \
	 CROSS=$(TARGET_CROSS) \
	 $(SCONS) $(FOO_SCONS_OPTS)
endef

So I wrote my .mk file the same way. However scons does not seem to
find the Check library. Building galera fails with:

Checking for C header file check.h... no
Error: check header file not found or not usable

and corresponding config.log shows a "check.h: file not found" error.

Now the disturbing thing is that it only happens when I build on a
system on which check is not installed system-wise. If the build host
has check installed, galera builds. Does this mean that scons uses
host haeders instead of those provided by buildroot packages? Any idea
how to make it behave properly?

Cheers,
