Comment (by slyfox):

 For me ghc creates /tmp/cc* files on every linkage:

 {{{
 $ ls -l /tmp/cc* | grep slyfox
 <none>

 $ echo 'main = print 1' > a.hs

 $ inplace/bin/ghc-stage2 --make a.hs

 $ ls -l /tmp/cc* | grep slyfox
 -rw------- 1 slyfox   users     3295 Jan 18 22:37 /tmp/cch5o5Wp

 $ cat /tmp/cch5o5Wp
 -plugin
 /usr/libexec/gcc/x86_64-pc-linux-gnu/5.3.0/liblto_plugin.so
 -plugin-opt=/usr/libexec/gcc/x86_64-pc-linux-gnu/5.3.0/lto-wrapper
 -plugin-opt=-fresolution=/tmp/ccM7O6lz.res
 -plugin-opt=-pass-through=-lgcc
 -plugin-opt=-pass-through=-lgcc_s
 -plugin-opt=-pass-through=-lc
 -plugin-opt=-pass-through=-lgcc
 -plugin-opt=-pass-through=-lgcc_s
 --eh-frame-hdr
 -m
 elf_x86_64
 -dynamic-linker
 /lib64/ld-linux-x86-64.so.2
 -o
 a
 ...
 }}}

 Do other people see the ~same contents in orphan /tmp/cc* files?
