# Builds a Libjpeg framework for the iPhone and the iPhone Simulator.
# Creates a set of universal libraries that can be used on an iPhone and in the
# iPhone simulator. Then creates a pseudo-framework to make using libjpeg in Xcode
# less painful.
#
# To configure the script, define:
# IPHONE_SDKVERSION: iPhone SDK version (e.g. 8.1)
#
# Then go get the source tar.bz of the libjpeg you want to build, shove it in the
# same directory as this script, and run "./libjpeg.sh". Grab a cuppa. And voila.

I had the same error. In my config.log it was saying -mios-simulator-version-min=11.4, ios 10 is the maximum deployment target for 32-bit targets. So I changed the minimum version to 7.0 and it worked. 7.0 was just my preference, I guess you can set it to 10.

Apple is making it difficult for you to compile 32-bit outputs. Better just compile for 64-bit. Also, i've the files are no more 'fat' so removed (commented) lipo related code. Here is my file:
