avro-c++: Fix build for 32-bit targets
Building avro-c++ for 32-bit targets currently fails due to the following warnings being treated as errors: - `useless-cast` in Symbol.cc - `conversion` in FileStream.cc These are promoted to errors because of `-Werror` in the project's build flags. Fix: lib32-avro-c++/1.12/sources/avro-c++-1.12/lang/c++/impl/parsing/Symbol.cc:91:27: error: useless cast to type 'int' [-Werror=useless-cast] 91 | adj.push_back(static_cast(it - rs.begin())); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ cc1plus: all warnings being treated as errors lib32-avro-c++/1.12/sources/avro-c++-1.12/lang/c++/impl/FileStream.cc:208:41: error: conversion from 'int64_t' {aka 'long long int'} to 'size_t' {aka 'unsigned int'} may change value [-Werror=conversion] 208 | in_->seek(position - byteCount_ - available_); | ~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~ lib32-avro-c++/1.12/sources/avro-c++-1.12/lang/c++/impl/FileStream.cc:209:22: error: conversion from 'int64_t' {aka 'long long int'} to 'size_t' {aka 'unsigned int'} may change value [-Werror=conversion] 209 | byteCount_ = position; | ^~~~~~~~ cc1plus: all warnings being treated as errors Signed-off-by: Alper Ak <alperyasinak1@gmail.com> Signed-off-by: Khem Raj <raj.khem@gmail.com>

32# A patch has been submitted upstream: https://github.com/apache/avro/pull/3433
33# Once this or an equivalent fix is merged and the recipe upgraded, this can be removed.

35# These errors don't occur when using Clang accordingly to upstream configuration and
36# the workaround flags aren't recognized by Clang either.
37# To avoid unnecessary warnings and keep the build clean across toolchains, the flags are conditionally added
38# using the toolchain-gcc override. This makes it unnecessary to override anything for Clang.
