+Subject: [PATCH] strpool: don't mix up host/build flags when cross compiling
+
+Submitted upstream as https://bugs.freedesktop.org/show_bug.cgi?id=60364
+
+Commit b71035ce89 (build-sys: modernize build system) changed the strpool
+(which needs to be built for the build machine) compilation to use
+AM_CFLAGS / AM_LDFLAGS rather than CFLAGS / LDFLAGS. This is wrong, as
+The AM_ version is used TOGETHER with (the user supplied) CFLAGS/LDFLAGS,
+causing strpool to use both CFLAGS (for host) and CCFLAGS_FOR_BUILD (for
+build) flags, breaking cross compilation with errors like:
+
+cc1: error: unrecognized command line option "-mabi=spe"
+
+Instead overwrite the (user supplied) CFLAGS with the (user supplied)
+CFLAGS_FOR_BUILD (and similar for LDFLAGS) like we used to do.
