openblas: fix build with old binutils versions
Older toolchains that use binutils <= 2.23.2 are affected by binutils bug #14887 (https://sourceware.org/bugzilla/show_bug.cgi?id=14887), where: someinstruction [ foo, something ] is not accepted, due to the whitespace after [ and before ], causing the following build failures for OpenBLAS: ARM register expected -- `pld [ r1,#512 ]' Since we don't have any mechanism to add dependencies on binutils versions, we work around this problem by patching the code to remove the problematic whitespaces. As there are many many instances of this in the ARM assembly code of OpenBLAS, we use a sed expression to make this modification rather than a patch. Fixes: http://autobuild.buildroot.net/results/43e50b480b4aea0fdec745d7875c85377c114cac/ [Peter: use single quotes in sed invocation] Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
