[Buildroot] [PATCH] package/erlang: patch the tarball

[Johan Oudinet]

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).

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!
