[oe] problems compiling glibc_2.9-r37.4 under Angstrom

[Víctor M. Jáquez L.]

In order to build native-sdk-image recipe, I found my self compiling
glibc_2.9-r37.4, because it is the real provider of virtual-libc-dev (the
toolchain does not truly provide it -but that is another bug [1]-).

But the glibc_2.9-r37.4 configuration fails using the canonical
arm-angstrom-linux-gnueabi- toolchain (using the csl external toolchain fails
too, but for other reasons):

Log data follows:

Reading the config.log I found:

So, the problem is that the pre-processor is _unable_ to find the *correct*
header limits.h. Why? Because it does not exist in the sysroot!!!!

$ find tmp-angstrom_2008_1/sysroots/armv7a-angstrom-linux-gnueabi/ -name "limits.h"
tmp-angstrom_2008_1/sysroots/armv7a-angstrom-linux-gnueabi/usr/lib/gcc/arm-angstrom-linux-gnueabi/4.3.3/include-fixed/limits.h
tmp-angstrom_2008_1/sysroots/armv7a-angstrom-linux-gnueabi/usr/include/c++/4.3.3/tr1/limits.h
tmp-angstrom_2008_1/sysroots/armv7a-angstrom-linux-gnueabi/usr/include/linux/limits.h

Why? Why the toolchain does not install a sane limits.h in a sane directory?

Thanks.
