+Subject: [PATCH] scripts: Use fixed input and output files instead of pipe for
+ here-doc
+There was a bug of "as" in binutils that when it checks if the input file and
+output file are the same one, it would not check if they are on the same block
+device. The check is introduced by the following commit in v2.31.
+The here-doc usage in this script creates temporary file in /tmp. When we run in
+an environment where /tmp has rarely been used, the newly created temporary file
+may have a very low inode number. If the inode number was 6 which is the same as
+/dev/null, the as would wrongly think the input file and the output file are the
+same and report the following error.
+*** Compiler lacks asm-goto support.. Stop.
+One observed case happened in docker where the /tmp could be so rarely used that
+very low number inode may be allocated and triggers the error.
+The fix below for the bug only exists on the master branch of binutils so far
+and has not been released from upstream. As the convict is introduced since
+v2.31, only v2.31 is affected.
+When building linux-libc-headers we need to use "as" in binutils which does not
+contain the fix for the moment. To work around the error, we create a fixed
+temporary file to contain the program being tested.
+This patch also removes ">/dev/null 2>&1" so we will have more direct error
+information in case something else wrong happened.
+Upstream-Status: Inappropriate [A work around for binutils v2.31]
