zephyr-core/zephyr-kernel: Fix arm32 binutils 2.40 incompatibility

Armv7 boards are currently failing with binutils 2.40 if certain
statements are combined on the same line without a semicolon. Introduce
a patch to fix this by inserting a semicolon.

+Subject: [PATCH] toolchain: gcc: Fix separator between directives on same
+ line
+
+The Arm assembler in binutils 2.40 contains a change [1] which affects
+how multiple directives on the same line are parsed.
+
+Previously, the following combination of directives parsed successfully:
+
+    .code 32 .balign 4
+
+With binutils 2.40, the following error is now seen:
+
+    Error: junk at end of line, first unrecognised character is `.'
+
+To fix, insert a semicolon after '.code 32', as there already is after
+'.thumb'.
