Makedumpfile compile errors on Debian 10

[Jiang Wang .]

Hi there,

I tried to compile version 1.6.7 and master on Debian 10 and got
following error:

To fix it, I have to make the following change:
diff --git a/Makefile b/Makefile
index 388faf7..7006f81 100644
--- a/Makefile
+++ b/Makefile
@@ -65,7 +65,7 @@ LIBS := -lsnappy $(LIBS)
 CFLAGS += -DUSESNAPPY
 endif

 try-run = $(shell set -e;              \
        TMP=".$$$$.tmp";                \
Not sure if it is an issue of Debian or makedumpfile. If it is the
latter, please fix the Makefile. Thanks.
Also, I tried the master and version 1.6.7 on Linux kernel 5.10 and
got a kernel not supported error. Do we know when 5.10 will be
supported? Thanks.

Jiang
