I'm building boost using a cross compiler (gcc 4.8.2) for solaris 10
sparc. Boost built fine in 1.57.0, but starting in 1.58.0, two new
flags were being passed to g++ that broke compilation. Here is an
example compilation from boost 1.57.0, 1.58.0, and 1.59.0-rc2. The
notable flag changes are -mcpu=c3 and -m32 in 1.58.0 and -mcpu=v7 and
-m32 in 1.59.0-rc2. These weren't present in 1.57.0. Does anyone have
any ideas about what might be going on here? Thanks so much!

1.57.0:
"/opt/pl-build-tools/bin/sparc-sun-solaris2.10-g++"
-ftemplate-depth-128 -std=c++11 -fPIC -O3 -finline-functions
-Wno-inline -Wall -pthreads  -DBOOST_ALL_NO_LIB=1 -DNDEBUG
-D_XOPEN_SOURCE=600  -I"." -c -o
"boost/bin.v2/libs/program_options/build/gcc-4.8.2/release/link-static/threading-multi/cmdline.o"
"libs/program_options/src/cmdline.cpp"

This succeeds.

1.58.0:
"/opt/pl-build-tools/bin/sparc-sun-solaris2.10-g++"
-ftemplate-depth-128 -std=c++11 -fPIC -O3 -finline-functions
-Wno-inline -Wall -mcpu=c3 -pthreads -m32  -DBOOST_ALL_NO_LIB=1
-DNDEBUG -D_XOPEN_SOURCE=600  -I"." -c -o
"boost/bin.v2/libs/program_options/build/gcc-4.8.2/release/link-static/threading-multi/cmdline.o"
"libs/program_options/src/cmdline.cpp"

This fails with errors such as:
sparc-sun-solaris2.10-g++: error: unrecognized argument in option '-mcpu=c3'
sparc-sun-solaris2.10-g++: note: valid arguments to '-mcpu=' are:
cypress f930 f934 hypersparc leon native niagara niagara2 niagara3
niagara4 sparclet sparclite sparclite86x supersparc tsc701 ultrasparc
ultrasparc3 v7 v8 v9

1.59.0-rc2:
"/opt/pl-build-tools/bin/sparc-sun-solaris2.10-g++"
-ftemplate-depth-128 -std=c++11 -fPIC -O3 -finline-functions
-Wno-inline -Wall -mcpu=v7 -pthreads -m32  -DBOOST_ALL_NO_LIB=1
-DNDEBUG -D_XOPEN_SOURCE=600  -I"." -c -o
"boost/bin.v2/libs/program_options/build/gcc-4.8.2/release/link-static/threading-multi/cmdline.o"
"libs/program_options/src/cmdline.cpp"

This fails with errors such as:
/var/tmp//cc6Xl0Mh.s: Assembler messages:
/var/tmp//cc6Xl0Mh.s:2119: Error: Architecture mismatch on "cas".
/var/tmp//cc6Xl0Mh.s:2119:  (Requires v9|v9a|v9b; requested architecture is v8.)
