compiling with Wcast-align shows a huge number of warnings for THUMB
When compiling with Wcast-align and build traged beeing THUMB a huge number of warnings is shown.
RIOT uses Wcast-align by default i switched it of for the libwarm.a generation.

[100%] Linking C static library libwamr.a
[100%] Built target wamr
Hi, have you found any issue when using WAMR in Thumb? If not, could you please disable -Wcast-align
when building libwarm.a? It really takes effort to clear the warnings, which aren't reported by other targets.
Thanks for taking a look. For the moment i removed that FLAG for the compilation of WAMR on RIOT, which uses it throughout most of its build process and allready spotted a number of (security) bugs.
I just wanted to make you aware of this issue. -and me-
Please have this open as a reminder until it is solved
