package/erlang: patch the tarball

Remove the lib/ssl/src/deps directory before configuring the package. Otherwise, during the compilation of the ssl app, it may fails by looking for logger.hrl in the wrong location (bootstrap/lib/kernel instead of lib/kernel).

Hi Johan,

Thanks for getting to the bottom of this.
I was investigating this and had the following config which consistently failed with the logger.hrl file not being found.

BR2_arm=y
BR2_cortex_a9=y
BR2_ARM_ENABLE_VFP=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_CUSTOM=y BR2_TOOLCHAIN_EXTERNAL_DOWNLOAD=y BR2_TOOLCHAIN_EXTERNAL_URL="http://autobuild.buildroot.org/toolchains/ tarballs/br-arm-cortex-a9-glibc-2019.11.tar.bz2" BR2_TOOLCHAIN_EXTERNAL_GCC_9=y BR2_TOOLCHAIN_EXTERNAL_HEADERS_5_3=y BR2_TOOLCHAIN_EXTERNAL_CUSTOM_GLIBC=y BR2_TOOLCHAIN_EXTERNAL_CXX=y
BR2_PACKAGE_OPENSSL=y
BR2_PACKAGE_ERLANG=y

Applying this patch solves the issue.

Best regards,
Frank

Thanks for this work! A link to the autobuilder failure fixed by this commit was missing in your commit log, so I added it and applied to master. Thanks!
