Could you provide a reasonably minimal defconfig that exhibits the
issue? I'm not able to reproduce. libzip alone, or libzip + openssl
builds fine here with a uClibc pre-built toolchain.

Thanks,

Thomas

Paul, Al,

Applied to master, thanks.

Note that I was a bit puzzled like Thomas, but your defconfig hinted at
the cause: yours is using libressl, while I guess Thomas only tested
with openssl.

And indeed, here's an even simpler defconfig that exhibit the issue:

    BR2_arm=y
    BR2_cortex_a7=y
    BR2_TOOLCHAIN_EXTERNAL=y
    BR2_TOOLCHAIN_EXTERNAL_BOOTLIN=y
    BR2_TOOLCHAIN_EXTERNAL_BOOTLIN_ARMV7_EABIHF_UCLIBC_STABLE=y
    BR2_PACKAGE_LIBZIP=y
    BR2_PACKAGE_OPENSSL=y
    BR2_PACKAGE_LIBRESSL=y

Thanks! :-)

Regards,
Yann E. MORIN.
