It turns out that all of my testing of the analyzer has been with
--enable-host-shared; on building without it, the link of the plugin
failed with messages like this for all of the .o file:
/usr/bin/ld: analyzer/analysis-plan.o: relocation R_X86_64_32 against
`.rodata' can not be used when making a shared object; recompile with -fPIC
This patch adds a PLUGIN_CFLAGS to the Makefile.in and automatically
adds it to the CFLAGS of all .o files for in-tree plugins.
PLUGIN_CFLAGS has -fPIC, fixing the link error.
Successfully bootstrapped & regrtested on x86_64-pc-linux-gnu.
Pushed to branch "dmalcolm/analyzer" on the GCC git mirror.
gcc/ChangeLog:
* Makefile.in (PLUGIN_CFLAGS): New. Add it to CFLAGS of
all .o files for in-tree plugins.
