mongrel2: Needs a glibc or a uClibc-0.9.34-git based toolchain

From: Markos Chandras <markos.chandras@imgtec.com>

mongrel2 needs the {get,make,swap}context functions which are
present in glibc and in the uClibc's master branch.

An external toolchain can be uClibc based... but we don't know which
version. However, since no uClibc stable release has been released with
this feature, I don't expect any external toolchain today to have this
feature enabled. So something like:

	depends on BR2_UCLIBC_VERSION_SNAPSHOT || \
		external toolchain uses glibc or eglibc || \
		crosstool-ng backend has glibc or eglibc selected

Would probably be more appropriate.

Best regards,

Thomas

Hi Thomas,

No problem. Although I can't find an option for external toolchain +
eglibc. So what I have right now is this:

        # {get,make,swap}context functions present in
        # {e,}glibc and in uClibc's master branch.
        depends on BR2_UCLIBC_VERSION_SNAPSHOT || \
                BR2_TOOLCHAIN_CTNG_eglibc || \
                BR2_TOOLCHAIN_CTNG_glibc || \
                BR2_TOOLCHAIN_EXTERNAL_CUSTOM_GLIBC || \
                BR2_TOOLCHAIN_EXTERNAL_GLIBC

I believe this should cover all the cases. Thanks for the review

Dear Markos Chandras,

Yes, in the external toolchain backend, we support eglibc and glibc
similarly, so there's just one single option for both.

It is however not needed to put BR2_TOOLCHAIN_EXTERNAL_CUSTOM_GLIBC in
your condition, because it already selects
BR2_TOOLCHAIN_EXTERNAL_GLIBC. So as far as external toolchains are
concerned, "depends on BR2_TOOLCHAIN_EXTERNAL_GLIBC" is enough.

Thanks,

Thomas

Hi Thomas,

Thank you for the clarification. I will prepare a new patch.
