I think, it is as simple as this:
Index: compiled.mk
===================================================================
--- compiled.mk (revision 317825)
+++ compiled.mk (working copy)
@@ -12,9 +12,7 @@
BJAM_ARGS= --layout=system \
--prefix=${PREFIX}
-.if ${ARCH} == amd64
-BJAM_ARGS+= cxxflags=-fPIC
-.endif
+BJAM_ARGS+= cxxflags="${CXXFLAGS:N-O*}" cflags="${CFLAGS:N-O*}"
NO_CCACHE= yes
.if ${CC:T:Mgcc*}
I make sure to remove any -O* flags from the local settings, because boost
prefers to be compiled with -O3 and inserts that in place automatically -- there
is no good reason to overwrite that.
Also, it seems, the upstream wised up on the -fPIC flag -- it is now added,
where needed. Adding it, where /not/ needed (in static libraries and
executables), as the current compiled.mk is doing on amd64, only pessimises the
generated code a little bit.
